Question

What is meant by saying that latent heat of vaporization of water to 226 kj/kg^-1 ?

Answer 1

• 226 kJ/kg^-1 means that when one kg of water at its boiling point temperature changes into steam, 226 kJ of heat is absorbed.
• The term latent heat of vaporization can be defined as the amount of heat needed for the conversion of 1kg of liquid at its boiling point to gas at same temperature.
