08.22: In a calorimesd8gfc4;2f8 sko s7a zter, 20 grams of liquid water at $100^{\circ}C$ is mixed with 50 grams of water vapor at $100^{\circ}C$. The system is allowed to come to equilibrium. Assuming that the calorimeter and the surroundings can be ignored, which of the following best describes the net energy exchange between the vapor and the liquid during the process of coming to equilibrium?

A. There is no net energy exchange.

B. Energy is transferred from the vapor to the liquid, vaporizing some of the liquid

C. Energy is transferred from the vapor to the liquid, increasing the liquid’s temperature.

D. Energy is transferred from the vapor to the liquid until all of the liquid vaporizes.

E. Energy is transferred from the liquid to the vapor, condensing some vapor
