SSC MTS EXAM

Detailed explanation-1: -The amount of potential energy necessary for a phase change to gaseous form is called the heat of vaporization. The heat gained or lost during a temperature change is given by, Q = m c t . The heat gained or lost during a phase change of solid to liquid is given by, Q = m H f .

Detailed explanation-2: -Experiments show that the heat transferred to or from a substance depends on three factors-the change in the substance’s temperature, the mass of the substance, and certain physical properties related to the phase of the substance.
