What is Heat Energy?
We encounter heat energy everywhere, including in icebergs, volcanoes, and our own bodies. There is heat energy in all stuff.
Heat energy is the only thing that results from the movement of tiny particles known as atoms, molecules, or ions in liquids, solids, and gases. One substance may absorb heat energy from another, and the flow caused by a temperature differential between two things is referred to as heat.
The ratio of heat extracted from the cold reservoir to the work supplied to the pump is known as the coefficient of performance of a refrigerator (= heat pump used for purpose of cooling of cooling):
Since COP = Q c/W, Q c = W COP.
Energy conservation dictates that the net energy transferred to the refrigerator by labour and heat must equal zero throughout the course of one cycle. It follows that heat rejected to the hot reservoir equals heat taken from the cool reservoir plus labor performed.
Q h = Q c + W
= (COP)W
= (1.4)20J
= 88J
