Heat transfer is the exchange of thermal energy between physical systems, depending on the temperature and pressure, by dissipating heat.The fundamental modes of heat transfer are conduction or diffusion, convection and radiation.eat transfer is the exchange of thermal energy between physical systems, depending on the temperature and pressure, by dissipating heat.
The direction of heat transfer is from a region of high temperature to another region of lower temperature, and is governed by the Second Law of Thermodynamics. Heat transfer changes the internal energy of the systems from which and to which the energy is transferred. Heat transfer will occur in a direction that increases the entropy of the collection of systems. Thermal equilibrium is reached when all involved bodies and the surroundings reach the same temperature.
