WebThermal energy refers to the energy contained within a system that is responsible for its temperature. Heat is the flow of thermal energy. A whole branch of physics, thermodynamics, deals with how heat is transferred between different systems and how work is done in the process (see the 1ˢᵗ law of thermodynamics). Web7 de oct. de 2016 · The mass heat capacity (per unit mass) of a body, also called specific heat, is the body’s ability to store heat. This is precisely defined as the amount of heat required to raise the temperature of a 1kg mass by 1°C. As we have seen, it is 4.18 kJoules/kg/°C for liquid water (4.18 Joules per 1 g). This is a particularly high value.
