Formula of heat transfer
WebLatent heat (also known as latent energy or heat of transformation) is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process — usually a first-order phase transition.. Latent heat can be understood as energy in hidden form which is supplied or extracted to change the state of a substance without changing … WebHeat by conduction takes place when two objects are kept in direct contact. Also, the temperature of one is higher than the other. The temperature tends to equalize and due to which the heat conduction consists of the transfer of kinetic energy from warmer medium to a cooler one. We denote heat is denoted by Q. The Heat formula is: C =.
