Question

define latent heat of vapourization?describe method for determination of latent heat of vapourization of steam

Answer 1

Answer:

it is define as the heat required to change one mole of liquid at its boiling point under standard atmospheric pressure..

it is expressed as kg/mol.....

the heat of vaporization of water is about 2,260Kj/Kg ..

Answer 2

Latent heat of vaporisation it is the energy (heat) required to transform a liquid mass at the boiling point (for example, water at 100°C at normal pressure) from liquid to gas. It is called "latent" (not seen, not registered) since this energy flow do not change the temperature so we can not "see" it.
