Thermodynamic process

A thermodynamic process describes how a system—like a gas or a metal—changes in energy, temperature, pressure, or volume. It focuses on the transfer of heat and work as the system undergoes transformations, such as heating, cooling, compression, or expansion. These processes follow the laws of thermodynamics, which govern energy conservation and entropy. Understanding these processes helps explain how engines work, how refrigerators cool, and how natural phenomena occur, by analyzing how energy moves and transforms within different systems during various physical changes.
