WebSpecific heat is closely related to the concept of heat capacity. Heat capacity is the amount of heat necessary to change the temperature of a substance by 1.00 °C . In equation form, heat capacity C is C = m c, where m is mass and c is specific heat. Note that heat … WebHeat transfer is the transfer of thermal energy from one body to another. This can happen through three primary mechanisms: conduction, convection, and radiation. The rate of heat transfer, represented by the symbol Q, is the amount of heat that flows per unit of time.
