Thermodynamics is a branch of physics that studies how heat (energy) moves between different objects. In thermodynamics, equations are used to help scientists and engineers better understand the behavior of heat in different systems. A table of thermodynamic equations is a list of the different equations used to describe heat-related processes. Each equation has a specific purpose—like predicting how much heat energy is released or absorbed when something is heated or cooled—and each equation must include certain information related to the process. For example, for an equation predicting the amount of heat released when something is heated, the equation must include the temperature of the object at the beginning and end of the process, as well as the amount of energy needed to produce the heat. By having a table of all the equations in one place, it is easier to find and use the right equation when studying thermodynamics.
