👉 A thermodynamician is a scientist who studies the behavior of matter and energy in the context of thermodynamics, which is the branch of physics that deals with heat, work, and other forms of energy. Thermodynamics is used to understand how systems like fluids, gases, and materials behave under various conditions. A thermodynamician uses equations of state to calculate the probabilities of states, and they often study the behavior of substances in a variety of physical processes, including heat transfer, phase transitions, and
