Did You Know?
Thermodynamics is based on the fact that all forms of energy, including heat and mechanical energy, are basically the same. Thus, it deals with the ways in which one form of energy is converted into another, when one of the forms is heat. The study of thermodynamics dates from before the invention of the first practical steam engine--an engine that uses steam to produce physical power--in the 18th century. Today most of the world's electrical power is actually produced by steam engines, and the principal use of thermodynamics is in power production.
