as heat is transferred from something to something else , the temperature of that something will decrease & heat transferred from a liquid to the environment ->  the temperature of the liquid will decrease  the temperature of the liquid will decrease & temperature is a measure of heat energy ->  the heat energy of the liquid will decrease  the heat energy of the liquid will decrease & freezing means a substance changes from a liquid into a solid by decreasing heat energy ->  the liquid may freeze if the heat energy of the liquid is decreasing  the temperature of the liquid will decrease & the liquid may freeze if the heat energy of the liquid is decreasing -> if heat of a liquid is transferred to the environment, then the temperature of the liquid will decrease and the liquid may freeze
