Molar specific heat at constant volume of an ideal diatomic gas is `(5)/(2)R`
On heating one mole of an ideal diatomic gas through `1^(@)C` at constant pressure the increase in internal energy of gas is `(7)/(2)R` .

Text Solution

Verified by Experts

`C_(v)=(3)/(20R` and `C_(p) =(3)/(2) R +x = (3)/(2) R +R (R =x)`
Also `c_(v) =DeltaU`
Icrease in internal energy for diatomic gas at constnat `P =(5)/(2)R` .
