¹⁵This process is very similar to water that isn’t at boiling temperature, some molecules have enough energy to evaporate to the gas state. At the same time, some water molecules in the gas state may lose energy and go to the liquid state again. In a closed environment, a dynamic equilibrium results in which the number of evaporating molecules equals the number of condensating molecules. Below boiling temperature the vast majority of water molecules is in the liquid state.
