If `C_(p) and C_(v)` denoted the specific heats of unit mass of nitrogen at constant pressure and volume respectively, then

A

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

B

`C_(p)-C_(v)=(R )/(7)`

C

`C_(p)-C_(v)=(R )/(14)`

D

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

Text Solution

Verified by Experts

The correct Answer is:
A
using Mayers equation, for 1 mole of gas,
`C_(P)-C_(V)=R`
`therefore"for unit mass,"C_(P)-C_(V)=R/M=(R)/(28)`
`" "(therefore"M for nitrogen=28)"`
