Explain why Cp > Cv ?
Hi Sudip!
In this derivation, you’ll need a basic knowledge of differentiation (calculus, grd-XII)
First law of thermodynamics states that, DQ = DU + PDV
Now, specific heat constant is actually rate of change of heat with respect to that of temperature.
At constant volume, ∆V = 0

Or, CP – CV = R
As R is always positive, CP > CV
Hence proved.
Hope it is clear!
Best wishes!!
