heat meaning

EN[hiːt] [-iːt]
  • In physics, heat is energy in transfer other than as work or by transfer of matter. When there is a suitable physical pathway, heat flows from a hotter body to a colder one. The transfer results in a net increase in entropy.
  • Heat refers to a process of transfer between two systems, the system of interest, and its surroundings considered as a system, not to a state or property of a single system.
  • Kinetic theory explains heat as a macroscopic manifestation of the motions and interactions of microscopic constituents such as molecules and photons.
