- 1. Thermal physics is the branch of physics that deals with the study of heat and temperature and their relationship with energy and work. It explores how heat flows through different materials and systems, how temperature affects the properties of matter, and how thermal energy can be converted into other forms of energy. Thermal physics plays a crucial role in various fields such as engineering, meteorology, and environmental science, helping us understand concepts like thermodynamics, heat transfer, and thermal equilibrium. By studying thermal physics, scientists and engineers can design efficient heating and cooling systems, predict weather patterns, and develop sustainable energy sources.
