To understand why the specific heat of a gas at constant pressure (Cp) is always greater than its specific heat at constant volume (Cv), we can analyze the definitions and concepts involved. ### Step-by-Step Solution: 1. **Definitions of Specific Heat**: - Specific heat at constant volume (Cv) is defined as the amount of heat required to raise the temperature of a unit mass of a gas by one degree Celsius (or one Kelvin) while keeping the volume constant. - Specific heat at constant pressure (Cp) is defined as the amount of heat required to raise the temperature of a unit mass of a gas by one degree Celsius (or one Kelvin) while keeping the pressure constant. ...
