Why is Cp greater than CV?

 

${𝐶}_{\mathit{𝑝}}$ Cp is greater than ${𝐶}_{𝑣}$ Cv because:

• When a gas is heated at a constant volume, the work performed on it increases the system's internal energy.
• When a gas is heated under constant pressure, work is done to overcome the pressure, and the volume expands, resulting in a rise in the system's internal energy.
• As a result,Cp ${𝐶}_{𝑝}$ might be stated to be bigger than Cv${𝐶}_{𝑣}$.
• Where ${𝐶}_{𝑝}$Cp  Molar heat capacity at constant pressure, and ${𝐶}_{𝑣}$Cv molar heat capacity at constant volume.
