Thermal physics is a field of science that studies heat and temperature. It also involves the relationship between heat and work, and the interaction between microscopic particles.
Thermal physics is the combined study of thermodynamics, statistical mechanics, and kinetic theory of gases. It is typically designed for physics students and functions to provide a general introduction to each of three core heat-related subjects. Thermal physics is important because it can explain how the world works, from large-scale processes in black holes and the formation of the early universe to the distribution of heat. The term thermal physics is applied to the study of the properties of large assemblies of atoms and to the interactions between such bodies, when there are differences of temperature between the bodies. Thermal physics involves the analysis of temperature and heat. It is the term used to describe the energy transfer between two objects with different temperatures, moving from the hotter object to the cooler one.
