During the process of evaporation, some molecules escape from the surface of a liquid. Which row correctly describes the average kinetic energy of the remaining molecules in the liquid and the corresponding change in temperature of the liquid?
| Average kinetic energy of remaining molecules | Temperature of the liquid | |
|---|---|---|
| A | decreases | decreases |
| B | decreases | increases |
| C | increases | decreases |
| D | increases | increases |
Average kinetic energy of remaining molecules: decreases; Temperature of the liquid: decreases
Average kinetic energy of remaining molecules: decreases; Temperature of the liquid: increases
Average kinetic energy of remaining molecules: increases; Temperature of the liquid: decreases
Average kinetic energy of remaining molecules: increases; Temperature of the liquid: increases
