Physics is the type of science that deals with the laws of nature. Thermodynamics is a field in physics that we will focus on today as well as the basic understanding of what perpetual motion machines are and the why and how they can’t exist.
Physics has a field in what is called “thermodynamics.” The field focuses on heat transfers between properties such as density, temperature, and pressure. Thermodynamics “focuses largely on how a heat transfer is related to various energy changes within a physical system undergoing a thermodynamic process,” usually guided by the laws of the field (Jones).
