Heat, q, is energy transferred between a system and its surroundings. For a process that involves a temperature change q=m⋅Cs⋅ΔT where Cs is specific heat and m is mass. Heat can also be transferred at a constant temperature when there is a change in state. For a process that involves a phase change q=n⋅ΔH where, n is the number of moles and ΔH is the enthalpy of fusion, vaporization, or sublimation. The following table provides the specific heat and enthalpy...
