An ideal gas having molar specific heat capaicty at constatnt volume is `3/2`R, the molar specific heat capacities at constant pressure is
A. `(1)/(2)R`
B. `(5)/(2)R`
C. `(7)/(2)R`
D. `(9)/(2)R`
A. `(1)/(2)R`
B. `(5)/(2)R`
C. `(7)/(2)R`
D. `(9)/(2)R`
Correct Answer – B
Here ,`C_(V)=(3)/(2)R`
Since `C_(P)-C_(V)=R`
`therefore C_(P)=C_(V)+R=(3)/(2)R+R=(5)/(2)R`
