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 capacity is the same as specific heat, but without any dependence on mass. WebNov 8, 2024 · This is a quasi-static isobaric process, which involves heat being transferred into the gas slowly (from a thermal reservoir that's barely warmer than the engine gas at every step of the process). The temperature of the gas rises during the process, and the volume increases, while heat comes into the system. The amount of heat transferred is:
