Heat formula physics class 11
WebHeat Engines and Heat Pumps Kelvin-Planck statement It is impossible to convert all the heat extracted from a hot body into work. In the heat engine, the working substance takes heat from the hot body, converts a part of it into work and gives the rest to the cold body.

WebMechanical energy or work (W) can be converted into heat (Q) by 1 W = JQ where J = Joule’s mechanical equivalent of heat. J is a conversion factor (not a physical quantity) and its value is 4.186 J/cal. Temperature Temperature of a body is the degree of hotness or coldness of the body.
