One mole of a monoatomic ideal gas is mixed with one mole of a diatomic ideal gas . The molar specific heat of the mixture at constant volume isA. `(3//2)R`B. `(5//2)`C. 2 RD. 4 R

Answer» Correct Answer - C
Molar specific heat of the mixture `C_(v)=(n_(1)C_(v_(1))+n_(2)C_(v_(2)))/(n_(1)+n_(2))`
`=(1xx(3)/(2)R+1xx(5)/(2)R)/(1+1)=2R`
