Explain the difference between heat capacity and specific heat of a substance. Heat capacity refers to the heat required to raise the temperature of a substance by 1 °C; specific heat refers to the heat required to raise the temperature of 1 gram of a substance by 1 °C. Thus, heat capacity is an intensive property, and specific heat is an extensive one. Specific heat refers to the heat required to raise the temperature of a substance by 1 °C; heat capacity refers to the heat required to raise the temperature of 1 gram of a substance by 1 °C. Thus, heat capacity is an intensive property, and specific heat is an extensive one. Heat capacity refers to the heat required to raise the temperature of a substance by 1 °C; specific heat refers
