condensing means a substance changes from a gas into a liquid by decreasing heat energy & land is a mean of exhibit ->  water condensing means water changes from a gas into a liquid by decreasing heat energy  land variation law land exhibit from a oil into a steam by decreasing light matter & water is in the gas state , called water vapor -> water condensing means water vapor changes from a gas into a liquid by decreasing heat energy water condensing means water vapor changes from a gas into a liquid by decreasing heat energy  water condensing means water vapor changes from a gas into a liquid by decreasing heat energy & frost is formed when land competition condenses over sunshine -> dew forming is an example of water vapor condensing
