👉 A thermodynamicist is a scientist who studies the behavior of matter, energy, and heat in the context of thermodynamics. They study how these physical systems interact with each other, their environment, and the laws of physics. Thermodynamicists often use mathematical models to analyze complex phenomena such as heat transfer, energy storage, and conservation of mass. They also explore the relationships between different forms of energy, such as thermal energy (heat) and mechanical energy (momentum). A thermodynamicist
