Interpretation: The given statement is to be evaluated and revised if incorrect.
Concept Introduction : Latent heat of vaporization is the amount of heat energy required to change the phase from liquid to vapor.
Answer to Problem 92A
The given statement is incorrect and the correct statement is the energy content of a substance is higher in the vapor phase than in the liquid phase at the same temperature.
Explanation of Solution
The heat supplied to liquid results in a rise in temperature until the boiling point is reached. After this point heat is continuously added but without a temperature rise. This thermal energy is used to break the bonds between molecules and cause a phase change. This energy enters or leaves a system during a phase change without causing a temperature change in the system and thus is known as latent (hidden) heat.
