Question

The latent heat of vaporization of water is 226kj/kg.what do you understand by the above statement?

Answer 1

The statement "The latent heat of vaporization of water is 226kj/kg." means the amount of heat energy needed to convert one kilogram of water from the liquid phase to vapor is 226kj/kg.

• Here, the term "latent" refers to a phase-changing process and the term "vaporization" refers to the phase change from liquid to gas.

• In other words, it means that when one kg of water at its boiling point temperature changes into steam, 226 kj of heat is absorbed.
