i think d...................... what you mean
Evaporation.
condensation
i think sweating maybe
the water's latent heat of vaporization is being pulled from the air, the water pulls heat from the room to undergo a phase change.
vaporization There are two forms of vaporization - evaporation and boiling
Latent heat is the measurement of energy needed to change the state of a substance at its melting point or boiling point. The latent heat of fusion of water is the amount of energy needed to change a fixed amount of water from a solid to liquid at 0 degrees C. this works out to be more than 800KJ of heat energy. The latent heat of vaporization of water is the amount of energy needed to change a fixed amount of water from a liquid to a gas at 100 degrees C. this is more than 1200KJ of heat needed to be absorbed.
When people sprinkle water on hot and dry roof on a sunny day, that water evaporates by taking energy from the ground, roof and surroundings. The evaporation of water causes a cooling effect because the large latent heat of vaporization of water helps to cool the hot surface.
The evaporation and vaporization of water is an endothermic process. As water vaporizes it absorbs heat energy. The changing of phase from liquid water to gas also means an increase in kinetic energy.
Vaporization is the change of liquid water to water vapor. Vaporization requires addition of the latent heat of vaporization to liquid water. The latent heat of vaporization supplies the liquid water molecules with enough energy to become vapor molecules. The latent heat of vaporization at 1.0 atmosphere pressure is about 1000 Btu per lbm ( 2260 kJ per kg ).
2260 kJ/kg
Perspiration coats the outside of the skin with moisture (water). The water evaporates. Evaporation requires heat to be absorbed by the water (the latent heat of vaporization). Heat is removed from the body surface to provide the water with the latent heat of vaporization.
condensationCondensation is where water vapor turns to liquid. The process is where gas turns to water then vapor and then turns back into liquid.
to prevent water from entering the calorimeter and allow only the gas.
By evaporation and vaporization.
