no picture or anything so cant anwser
Explanation:
Two major characteristics that change when air is heated and cooled is the density and the direction of the air flow. They change the movement of the air by heated air rises and cooled air doesn't.
By the use of a Accumulators
Q = heat energy , m=mass , c=specific heat , delta T= change in temperature
as you know heat is a form of energy which is <em>usually</em> measured in Joules according to the SI. and also we usually use kilograms for mass.
so you need to know the mass, specific heat, and change in temperature in order to find out the heat energy :)
