No, it is the 2nd. highest known.
NOTE: Which, actually, means that, yes, it is oneof the highest known.
2260 kJ/kg
The heat of fusion is the amount of heat (not temperature) required to change a solid to a liquid. It is also known as the melting point. The heat of vaporization is the amount of heat (not temperature) required to change a liquid to it's gaseous state. It is also know as it's boiling point.
maybe because of water vapor.
to prevent water from entering the calorimeter and allow only the gas.
thermol
yes
The heat of vaporization. :D
Heat of Vaporization id the amount of heat needed to transform a liquid into a gas while not raising its temperature.
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 ).
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.
The water heat of vaporization is 40,65 kJ/mol.
The latent heat of evaporation
The phase change of water into gas is vaporization. Vaporization in this example involves the liquid water absorbing heat (endothermically).
High heat of vaporization. It requires a great deal of energy to break the H bonds in water.
Water has a high heat of vaporization
2260 kJ/kg
vaporization of water happens when it turns from a liqued form into a gas due to heat which creates conensation :P
