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.

How fast body lose heat in cold water?
The rate at which the body loses heat in cold water depends on factors like water temperature, body composition, and level of physical activity. Generally, the body loses heat much faster in cold water compared to cold air, as water conducts heat away from the body 25 times faster than air. Hypothermia can occur in cold water in as little as 15 minutes.
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 fast does a body lose heat in cold water?
The rate at which a body loses heat in cold water depends on factors like water temperature, body size, clothing, and fitness levels. In general, the body loses heat much faster in water than in air because water conducts heat more efficiently, and cold water can lead to hypothermia quickly if exposed for an extended period without protection.
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 much faster is a divers body heat lost through conduction in water than in air?
A diver's body heat is lost around 25 times faster in water compared to air due to the higher thermal conductivity of water. Water conducts heat more efficiently than air, leading to faster heat loss when submerged in water.
How water is a good regulator of body temperature?
Water has a high specific heat capacity, meaning it can absorb and release large amounts of heat without changing temperature drastically. This property allows water in the body to absorb excess heat and help regulate body temperature by releasing it through sweating or evaporation. Water also has a high thermal conductivity, which helps distribute heat throughout the body efficiently.
How do you assume the help position to reduce heat loss and cold water how do you assume the help position to reduce heat loss in Cold water?
To reduce heat loss in cold water, you can assume the HELP position by huddling in a group, keeping as much of your body out of the water as possible, crossing your arms over your chest, and drawing your legs towards your chest. This position minimizes heat loss by reducing the surface area exposed to the cold water and helping to retain body 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.
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
