Mean kinetic energy of perfect gas is
$\propto$ T
$\propto$ T2
$\propto \dfrac{1}{T}$
$\propto \dfrac{1}{T^2}$
Next Question
Mass of gas is 300 gm and its specific heat at constant volume is 750J/kg K. if gas is heated through 75°C at constant pressure of 105 N/m2, it expands by volume 0.08 × 106 cm3. find CP/CV.
