The correct answer is Option 2.Explanation:CondensationThe process of conversion of water vapour into liquid is called Condensation.In other words, the water vapour in the air from your hot shower cooled when it came into contact with the cold mirror surface. As a result, the water vapour condensed, or turned into liquid form.SolidificationThe process by which a liquid becomes a solid is known as Solidification.When heat is lost from an object, the molecules slow down and form tighter bonds.MeltingThe process of conversion of a solid into a liquid is called Melting.Most substances are solid at low temperatures; as the temperature rises, they become liquid; and at higher temperatures, they become gaseous. EvaporationThe process of conversion of liquid into a gas is called Evaporation.
