Choose the correct statement regarding the behavior of water.
a. the water phase with the highest heat capacity is gas vapor.
b. the liquid-to-vapor phase change of water requires less energy than the ice-to-liquid phase change.
c. the water phase with the highest heat capacity is solid ice.
d. the energy required to evaporate 1 kg of liquid water equals the energy released when 1 kg of water vapor condenses into liquid.
e. the water phase with the smallest temperature increase when adding 10 kcal of heat is solid ice. tries 0/2

d. The energy required to evaporate 1 kg of liquid water equals the energy released when 1 kg of water vapor condenses into liquid.

Explanation:

Hello,

Since we're considering the same amount of water, the vapor phase has a higher energy content than the liquid phase, thus, for the specified amount of water particles (those contained in the given 1 kg) the energy MUST be same when taking them either to a gaseous phase or to a liquid phase, the only difference is the sign which is negative from gaseous to liquid (heat withdrawal) and positive from liquid to gaseous (heat adding).

Best regards.
