Evaporation is the process by which a liquid changes to, vapour., , Water exists in the liquid form at temperatures between 0°C and 100°C., But water changes to vapour at any temperature upto 100°C., Evaporation is the process by which a liquid changes to vapour. On, heating water, the heat absorbed is utilised for rise in temperature and, for evaporation., , Water has the ability to hold more heat (heat capacity) when, compared to other substances., , Some of the situations which make use of the high heat, capacity of water., , Water is used in radiators to regulate the heat in, automobile engines., , Water is used to cool hot objects., , Two thirds of the earth is water. This regulates the, temperature of the earth.
