Measurement of heat and internal energy

Measurement of heat and internal energy

We shall now deal with some of the calculations involved in heat and internal energy measurements. Since heat is a form of energy transfer, it is measured in joules the same as any other kind of energy. Now, the easiest way to produce heat, and at the
same time be able to measure it accurately in joules, is by an electrical method, but the explanation of this must wait until after we have studied electricity and its units (chapters 41 and 42). In the meantime we shall explain some of the terms used in our calculations.
