water is a kind of substance & condensing means a substance changes from a gas into a liquid by decreasing heat energy ->  water condensing means water changes from a gas to a liquid by decreasing heat energy  water condensing means water changes from a gas to a liquid by decreasing heat energy & water is in the liquid state, called liquid water & water is in the gas state , called water vapor ->  water condensing means water changes from water vapor to liquid water by decreasing heat energy  cooling means temperature decreases & temperature is a measure of heat energy ->  cooling means decreasing in heat energy  water condensing means water changes from water vapor to liquid water by decreasing heat energy & cooling means decreasing in heat energy & water vapor is rapidly cooled -> water vapor cooling causes that water vapor to condense into liquid water
