Answer to Question #144401 in Molecular Physics | Thermodynamics for Mosh

Question

one mole of a gas has a volume of 0.0223m^3 at a pressure of 101000pa at 0^c. if the molar capacity at constant pressure is 28.5jmol/k.calculate the molar heat capacity at constant volume.​

Answer 1

Solution

We know relation

$C_p-C_v=R$

Heat capacity at constant volume

$C_v=C_p-R=28.5-8.314$

$C_v=20.186J-mol/k$
