If `S_(P)` and `S_(V)` denote the specific heats of nitrogen gas per unit mass at constant pressure and constant volume respectively, then

A

`S_(p)S_(v)=28R`

B

`S_(p) S_(v)=R/28`

C

`S_(p)-S_(v)=14R`

D

`S_(p)-S_(v)=R`

Text Solution

Verified by Experts

The correct Answer is:
B
According to mayer.s relation `S_(p)-S_(v)=(R)/(m)`
For nitrogen, m=28
`S_(p)-S_(v)=(R)/(28)`
