Why is Chennai warmer than Srinagar?

Why are two thin blankets are warmer than a single blanket of double the thickness? When two thin blankets are held together, a layer of air is trapped in between them which is a bad conductor. So it prevents heat from our body to outside. It means it provides better insulation than a singe blanket of double size.

Air is trapped in the space between two thin blankets. Since air is an insulator of heat, it prevents the escape of body heat. That is why two thin blankets are usually warmer than one thick blanket.

Why do fluffy down comforters provide more warmth than thin cloth blankets? They trap more air. Air is a good insulator. ... If you place a heavy piece of canvas on top of a down sleeping bag, you will later feel colder than if you were to place the sleeping bag on top of the canvas.

In general, metals feel colder or hotter to the touch than other materials at the same temperature because they're good thermal conductors.

This means they easily transfer heat to colder objects or absorb heat from warmer objects..

Warmer air is less dense than cold, which is why warm air tends to rise and cold air sinks. Being acted on by gravity, colder, denser air weighs more and exerts greater pressure per unit area.

A new quilt is warmer because the air which is trapped inside the cotton or woollen clothing acts as an insulator and does not allow the transfer of heat. However, when the quilt gets older, the air spacing of the cotton or wool gets compressed it no longer remains a good insulator.

11–2–16, Brian. Why is the ocean warmer on the east coast than the west coast? ... However, the Pacific ocean is warmer as a whole than the Pacific because it is wider at the equator. The water has more time to travel along the equator and heat up before it moves to the poles compared to water in the Atlantic ocean.

In another words, water retains heat longer than air molecules as a result pool water stay warmer even at cool night similar to the hot day temperature, even though the night temperatures drop by 20 or 30 degrees from the day time temperatures.

Windsor's climate is modified by its location on the shores of the Great Lakes.

The water in the lakes ensures Windsor is warmer in winter and cooler in summer than it would otherwise be.

The lakes are also the source of Windsor's summer humidity, which many people find uncomfortable..

Why are some blankets "warmer" than others? It is actually the 'thermal conductivity' of the material that makes the difference. Think it as the material's capability to transfer(conduct) heat. The lower it is, the better it keeps you warm.

In the spring, the water takes time to heat up. ... In Fall, you are coming from Summer, a hot season, so your environment is still kind of hot from the previous season, therefore making Fall warmer than Spring.

Earth's seasonal lag is largely caused by the presence of large amounts of water, which has a high latent heat of freezing and of condensation. ... Due to seasonal lag, in the Northern Hemisphere the autumnal equinox (around Sept. 22) is considerably warmer than the vernal equinox (around Mar.

Is Cashmere Warmer Than Cotton? ... So yes, cashmere is a lot warmer than cotton when it comes to keeping someone warm for the winter. Cotton is easier to clean than cashmere which may be a reason why many people still wear it when the winter months hit.

Overall, Micro Puff insulation is lighter, warmer, and more packable than the aging Nano Puff tech, but it's also more expensive.

There are plenty of reasons why Nano Puff clothing is the right choice for many outdoor enthusiasts..

The reason why Thorium is the warmest of the two is due to its weight. ... Thorium weighs around 435 grams, whereas Cerium weighs 280 grams. That weight difference is due to the insulation, therefore, having a lot more down than Cerium, Thorium provides much better insulation and is the warmer of the two.

Overall, Micro Puff insulation is lighter, warmer, and more packable than the aging Nano Puff tech, but it's also more expensive. There are plenty of reasons why Nano Puff clothing is the right choice for many outdoor enthusiasts.

Teething If your child is teething, then his head might be getting warmer than usual. Teething causes the baby's head to get warmer. It is a normal response of the body and nothing to be too concerned about.

Since the resistance of the bulb is much more than the resistance of the wire, the bulb gets hot and the wire stays cool. ...

Light energy can be converted into heat energy. A black object absorbs all wavelengths of light and converts them into heat, so the object gets warm. ... A dark object of a given color will absorb more photons than a light object of the same color, so it will absorb more heat and get warmer.

The curvature of the Earth causes the Sun's energy to spread out over larger areas with increasing latitude. ... The amount of solar energy in a given area is greater at the equator than in an equal area at the poles, which is why the equator temperature is warmer than the polar temperatures.

1 Answer. Phillip E. The southern hemisphere is warmer than the northern hemisphere because more of its surface area is water.

Another physical process that affects DO concentrations is the relationship between water temperature and gas saturation. Cold water can hold more of any gas, in this case oxygen, than warmer water. Warmer water becomes "saturated" more easily with oxygen. As water becomes warmer it can hold less and less DO.

Convert -50F to C, if it's less than 10C, then -50F is colder, and it's more than 10C then it's warmer. Why does having the heat set to 68 Fahrenheit feel so much colder than having the AC set to68 Fahrenheit? ... What is the difference between -10 Celsius (14 F) and -40 Celsius (-40 F)?

Hence the lower part of a refrigerator is warmer, especially because it is shielded from the cold air flow by upper shelves and drawers. ... However, compartments at the top of the door are cooler than those at the bottom because they are somewhat closer to the cold air source at the top of the refrigerator.

The cloudy skies are like a blanket and the warmer air on the ground with us tries to leave and the clouds stop it from leaving. Warmer air will always try to move up and it cannot do so because of the clouds. That's why you might notice that cloudy nights are warmer than clear nights.

This is because buildings, sidewalks, and parking lots block heat coming from the ground from rising into the cold night sky. Because the heat is trapped on lower levels, the temperature is warmer. Urban heat islands can have worse air and water quality than their rural neighbors.

Warmer air is less dense than cold, which is why warm air tends to rise and cold air sinks. ... Being acted on by gravity, colder, denser air weighs more and exerts greater pressure per unit area.

London is experiencing hotter and drier summers that are further impacted by the Urban Heat Island effect (UHI).

The UHI can cause London to be up to 10'C warmer than neighbouring rural areas.

This is a result of the sun's rays being absorbed by hard surfaces rather than by vegetation such as trees, plants and grass..

The sea generally creates desirable temperatures statewide, creating warmer winters and cooler summers, especially in coastal regions of the state. Northern California has a moderately oceanic climate and generally receives higher annual rainfall amounts than southern portions of the state.

But after a while, when I go out of the sea, water seems to be warmer than air. Why? The water feels colder than the air because water is more conductive to heat. ... Water is a much better conductor than air, allowing for much faster heat transfer from your skin to the water and thus a colder sensation.

This is because of the Gulf Stream which warms the UK, which brings warm tropical water northwards from the equator. ... The United Kingdom is generally warmer than Canada during the winter. During the summer the United Kingdom is generally cooler than Canada. During the spring and the autumn there is not much difference.

The simple answer is ocean currents. ... If the air traveling to New York moves by land, it will be cooler than the air and currents that reach, for example, San Francisco. Thus, Rome is warmer than New York due to currents, geography and air movement patterns.

Why the discrepancy? It's actually warmer in the winter and cooler in the summer. That is, temperatures on the West Coast are more moderate overall. ... That means the West Coast experiences a climate more closely tied to its ocean, while the East Coast is getting its air from the continent.

As long as animal fur retains superior warmth and moisture resistant qualities to man made fibers, they will be valuable. ... Because fur is incredibly warm, that's why. Animal fur coats are much warmer than synthetic fibers, and also possess unique qualities in the deep cold. Furs remain the warmest material known to man.

While Tokyo and Seoul are similar in latitude, Tokyo has coastal island weather, nearby a vast ocean which tends to moderate its temperature. Seoul is inland and surrounded by mountains. ... All these make Seoul much colder. Shanghai is much farther south than both places and much warmer.

Alaska has the same amount of coastline as the rest of the states combined. Water tends to moderate temperatures better than land. ... They say Alaska has been warmer lately due to some sort of ocean current bringing warmer water up this direction. There are villages and towns in northern Canada- Nunavut for example.

Durban is in or near the subtropical dry forest biome whereas Cape Town is in or near the warm temperate dry forest biome. The average annual temperature is 3.9 °C (7°F) warmer. ... The altitude of the sun at midday is overall 4° higher in Durban than in Cape Town. Relative humidity levels are 1.4% higher.

When its snowing the air is drier (because all of the water's in the snow). Dry air doesn't conduct as well as wet air. This makes you feel warmer because you're losing less heat to the air. ... When it snows, chances are that relative humidity is higher than it was before it was snowing, so it should feel warmer.

It is because most of Europe has the advantage of the warm ocean current coming north from the tropics. ... There is then little interaction with colder air masses and colder ocean currents, so the overall weather in Europe is in general warmer that that seen in Alaska and Northern Canada.

Why is it hotter at the equator than it is at the poles? a. Because the equator is closer to the sun. ... Because the sun's rays hit the earth's surface at a higher angle at the equator.

Water has a higher heat capacity than soil and rock, so the ocean takes much longer to heat and to cool than the land. Coastal areas will generally have more moderate temperatures than inland areas because of the heat capacity of the ocean.

In the winter, wool keeps you warmer than cotton because wool fibers trap air pockets, helping to insulate you from the cold. ... When it is exposed to damp conditions, wool also has natural wicking properties that pull moisture away from your skin.

Is Alpaca Warmer than Sheep's Wool? YES, alpaca wool is warmer than sheep's wools, including merino.

Is Alpaca Warmer than Sheep's Wool? YES, alpaca wool is warmer than sheep's wools, including merino.

Blue Really Is The Warmest Color Our popular representation of heat is already the reverse of physics. Blue light is higher energy than red and requires a hotter radiation source, which is why red dwarf stars are much cooler than blue giants.

Because during the day, (that part of) the earth is in direct sunlight which is converted to heat energy. During the night, obviously there is no sunlight so the only source of heat is any residual warmth from the daytime. Why are days warmer than nights in summer?

Summer is warmer than winter (in each hemisphere) because the Sun's rays hit the Earth at a more direct angle during summer than during winter and also because the days are much longer than the nights during the summer. These effects are due to the tilt of the Earth's axis.

The Gulf Stream is part of the reason why Britain is warmer, but the difference between a maritime and a continental climate is more important. At the latitudes of Canada and Britain the prevailing winds are from the west. ... This is why Britain and coastal British Columbia have mild climates.

The curvature of the Earth causes the Sun's energy to spread out over larger areas with increasing latitude. ... The amount of solar energy in a given area is greater at the equator than in an equal area at the poles, which is why the equator temperature is warmer than the polar temperatures.

Thus, Spain, Italy and the Mediterranean in general are benefited by the currents. ... If the air traveling to New York moves by land, it will be cooler than the air and currents that reach, for example, San Francisco. Thus, Rome is warmer than New York due to currents, geography and air movement patterns.
