(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

1) According to Mayer’s equation,

C(p) – C(v) = R ------------ (1)

Where C(p) = specific heat at constant pressure

C(v) = specific heat at constant volume

R = Universal gas constant

But sometimes the above equation is used in the following way,

C(p) – C(v) = R/J ---------------- (2)

Where C(p) = gram molecular specific heat of the gas at constant pressure

C(v) = gram molecular specific heat of the gas at constant volume

R = Universal gas constant

J = Mechanical equivalent of heat

2. Relevant equations

3. The attempt at a solution

What are the units of C(p) & C(v) in equation(1)?
