Use the well-known formula: dQ=m.s.dt

where dQ=heat exchanged, m=Mass of the substance (water in this case), s=specific heat ( for water it is 1 calorie/gram-Kelvin) and dt=change in temperture

However, if the Water is in transition state from Ice, use: Q=m.L

L=Latent heat of fusion of Ice.

Generally, a few calories of heat are lost depending upon:

1. The mass of water

2. Humidity in air

3. Surface Area of Skin in contact with water

Say, for a little amount of water (take 5 gram)poured uniformly over unit skin area, the heat lost is 5 calorieprovided the temperature change is unity under ideally assumed conditions.

Does water conduct heat away from your body faster compared to air does?

Ok, lets assume that a pool of water and the air are at the same temperature. There are a number of ways you can lose heat to the surroundings, however in this example the most important reason is: Conduction. This is due to direct contact with surrounding particles. As the Particles in you body vibrate with energy they collide with surrounding air or water particles. You will thus lose much more energy to water than to air as water is much better at conducting heat away from you. (There are many times more water particles to transfer the energy away). In terms of heat capacity, if water has a higher heat capacity then it will take more energy from your body to heat it up. Seeing as you body is warmer than the surrounding water, the water will take more of your thermal energy to reach thermal equilibrium with you.


Can water viscosity affect how much heat a body of water absorbs?

The thinner the liquid is the faster it will absorb heat.


What happens to your body when it contains too much water?

There is that much of it it evaporates by any source of heat


How much faster does moisture transfer heat away from the body compared to air?

This depends on how hot your body is. However, in most cases it is almost the same.


How water is a good regulator of body temperature?

Water has an amazingly high specific heat compared to most substances so for example: adding or removing 1 Joule of energy from 1000 cm3 of water will change its temperature much less than it would change 1000 cm3 of most other substances.


How much water does the human body lose during activity?

When you do exercise, you sweat. This is a mechanism our body uses to get rid of excess heat.


How much faster does cold water rob the body of heat then clod air?

Water causes a rate of heat exchange approximately 25 times greater than air at the same temperature.Source: USAF Publications.


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.


How does sweating help humans to maintain a constant body temperture?

By sweating, your body removes some of the heat that is trapped in your body. When you sweat, water is released through the pores on your skin. The water/sweat that is on your skin contains some of the excess heat from inside your body. Eventually the sweat will evaporate or be wiped away, taking the excess heat with it.


Why do the temperature of the ground increase much more than the temperature of water?

because the ground absorbs more heat than a body of water that heat must be transfered to the ground water


What happens if an animal has to much of a vitamin?

If it is a fat soluble vitamin it is stored in you body fat, if it is a water soluble it is urinated away


Why do you get sun burnt faster wet than you do dry?

Water conducts heat much better than air, and that is due greater density of water. Therefore, your body will receive more heat from hot water than from hot air that is in contact with your skin.
