Question and answer
Q: Why does an evaporating liquid cool down, according to the Kinetic Molecular Theory?
A: liquid evaporates after acquiring kinetic energy as heat.As a vapor it leaves the vicinity or source of heat supply contact.Naturally ,since it was the heat energy that made it evaporate, [ and it is no longer in contact with this heat ,it is bound to loose kinetic energy, and as such cool down again to become liquid at normal temperature, and even solid as the heat loss continues. ]

User: The reduced vapor pressure at high altitudes causes a liquid to boil at a higherlower temperature.
