Question

For small coefficient of expansion in case of solid

• A. $C_p-C_v=R$
• B. $C_p-C_v=2R$
• C. $C_p$ is slightly greater than $C_v$
• D. $C_p$ is slightly less than $C_v$

Answer 1

The correct option is C $C_p$ is slightly greater than $C_v$

• Cp is slightly greater than Cv because constant pressure, the amount of heat added to increase the temperature of a system by 1 K gets distributed among increasing the internal energy of the system and in the volume of the system.
