   According to physics and thermodynamics, heat is energy transferred from one location in a body or thermodynamic system to another location, or across the boundary of one system to another one due to thermal contact even at that time when the systems are at distinct temperatures. It is furthermore often recounted as the process of move of energy between physical entities. In this recount, it is an energy that move to the body in any other way than due to work performed on the body.
   A related term is thermal energy, described as the energy of anybody that increases with the increase in temperature and volume. Heat is usually defined to as thermal energy, However, many definitions need this thermal energy to be in transfer between two systems to be called heat, otherwise, many sources prefer to continue to refer to the internal quantity as thermal energy.
   According to first law, heat energy might be changed to work. This usually observes in so-called heat engines, such as the steam engine. But in accordance with second law, these results in the overall govern that - to retain the "lost heat" small - the final temperature must be low. In compare, so-called heat pumps can take warmth at low temperatures from a "reservoir", e.g. from the earth, and deliver it via mechanism of electrical labor at a higher temperature for warming purposes. Now the temperature difference must be small, to retain the "lost electrical work" small.
