What else can I help you with?
What is the heat of vaporization of water in joules per kilogram?
The heat of vaporization of water is 2260 joules per kilogram.
What is the latent heat of vaporization of water in joules per kilogram?
The latent heat of vaporization of water is 2260 joules per kilogram.
Which substance is expected to have the highest heat of vaporization?
Water is expected to have the highest heat of vaporization among common substances.
What step changes liquid water to water vapor?
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 ).
How your body cooled when you perspire?
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.
How much heat does water release the when it evaporates?
The water heat of vaporization is 40,65 kJ/mol.
What is greater water heat of fusion or its heat of vaporization?
The heat of vaporization of water is greater than its heat of fusion. Specifically, the heat of vaporization is approximately 2260 joules per gram, while the heat of fusion is about 334 joules per gram. This means that it requires significantly more energy to convert water from a liquid to a gas than to change it from solid to liquid.
The amount of energy needed to change a material from a solid to a liquid is the heat of what?
The latent heat of evaporation
What information can be found in a water heat of vaporization table?
A water heat of vaporization table provides data on the amount of energy required to change a unit mass of liquid water into vapor at a specific temperature.
Is heat of vaporization for water is equal to heat on condensation of water?
Yes, the heat of vaporization for water is equal in magnitude but opposite in sign to the heat of condensation. This means that the amount of energy required to vaporize water is the same as the amount of energy released when water vapor condenses back into liquid water.
When water leaves a body of water after it is heated process is called?
The phase change of water into gas is vaporization. Vaporization in this example involves the liquid water absorbing heat (endothermically).
Does water have a low vapor pressure?
High heat of vaporization. It requires a great deal of energy to break the H bonds in water.
