The heat equation is a parabolic partial differential equation that describes the distribution of heat (or variation in temperature) in a given region over time.
In physics, heat is energy in a transfer between a system and its surroundings, other than as work or with the transfer of matter. In thermodynamics, finer detail of the process is unknowable.When there is a suitable physical pathway, heat flows from a hotter to a colder body.eat transfer that occurs with the system at constant temperature and that does change that particular state variable is called latent heat with respect to that variable. For infinitesimal changes, the total incremental heat transfer is then the sum of the latent and sensible heat increments.
