Temperature is defined as the measure of the average kinetic energy of the molecules of a substance, represented in a numerical scale with larger values indicating a greater average kinetic energy. However, this has not always been the case. The road to standardized temperature measurement has been a long one.
Historians date the first attempt to establish a temperature scale back to 130-200 B.C. by the Greek doctor Galeano, who ...
