The energy that is lost by the coffee and the mug is being transferred to the colder surroundings. We refer to this transfer of energy from the coffee and the mug to the surrounding air and countertop as heat. In this sense, heat is simply the transfer of energy from a hot object to a colder object.
What this means for us, in laymanâs terms, is that heated water has a tendency to rise upward and displace colder water. For example, when water is heated on a stove, hot water from the bottom of the pan rises, displacing the colder denser liquid which falls. Most hot water heaters are equipped with âheat trapsâ between the intake/outtake pipes and the heater itself.
