Why does water not heat up or cool off as air?
because the specific heat of water is very high
Does water heat up and cool down faster than air?
Air.You can always look up this answer on Bing or google!XD
Why does underwater lava differ from surface lava?
The lava itself is not different, it is the environment that is different. Water is much denser than air and has a higher heat capacity, meaning it takes more energy to heat it up. As a result, lava will lose heat to water extremely quickly, and so will cool much faster than it can on land.
What seeps into an aquifer when to much water is removed?
When too much groundwater is removed the ground subsides because the loss of water causes loose sediments underground to compact.
Water has a high latent heat capacity This means that?
They require alot more heat before their temperature start to rise, while others require less. These latter materials then takes much longer to cool down because they have more heat energy to give off.

How much water is used to make a car?
we need 8 tonnes of water just for one single car.(to cool down the heat of the metal on the car)
What should you do when you treating a casualty for heat exhaustion or heat stroke?
If they are still sweating and have normal-cool skin, remove them from the source of heat, elevate their legs and do what you can to cool them off. You can remove clothing, fan them, and try to give them sips of water. If their skin is dry and hot, remove them from heat and cool them down immediately. Apply cold packs to their necks, armpits, and groin. Wet them with cool water and fan them as much as possible. This is more serious and the patient should be transported immediately.

How much water should a casualty drink to treat heat cramps?
You should drink at least 16 to 32 ounces of water to treat heat cramps. This water will help cool the body down enough to let the cramps subside.
What cools off more slowly water or soil?
Water retains heat much better than soil, so in general the water will cool slower than the surrounding soil.
Why would sand cool faster than water in the dark?
The specific heat capacity of sand is much less than that of water. Hence sand cools earlier.
How much heat in kilojoules must be removed from glass of water that contains 100g of water to lower its temperature from 30 degrees Celsius to 15 degrees Celsius?
6.276 kJ
Why does a kettle have 800 watts?
Assuming you got that number off an electric kettle it is because that is how much power is needed to heat the water. The number of watts actually measure how much energy the kettle is designed to use. Water is very hard to heat compared to other liquids(or to cool). So it takes a lot of watts to get the kettle to heat the water.
Why do horseshoes cool by 900 degrees but the water temperature only rise by a few degrees?
This happens because there is so much more water than there is horseshoe. The heat from the horseshoe is distributed throughout the water, so the amount of heat per unit of water is lower than the original amount of heat per unit of horseshoe.
