Thermodynamics is study of energy on the molecular level, and how this energy can be harnessed to produce useful mechanical work. As the name thermodynamics implies, thermal energy can move as it is transferred from one body to another as heat. This flow of thermal energy can cause changes in the state of substances, or cause them to expand or contract. The industrial revolution was born when humans invented, and then improved upon, the steam engine our first attempt to harness the flow of thermal energy and convert a small portion of it into mechanical work. Our modern automobiles, refrigerators, and electrical power plants all run on thermodynamic heat transfer, and are ultimately governed by the laws of thermodynamics.Conceptual StrandThe principles and laws of thermodynamics are essential for understanding the concept of energy.Guiding QuestionHow do the laws of thermodynamics relate to understanding the conservation of energy?
