If `C_(P_` and `C_(v)` denote the specific heats nitrogen per unite mass at constant pressure and constant volume respectively, then
(1) `C_(P)-C_(v)=(R)/(28)` (2) `C_(P)-C_(v)=(R)/(14)`
(3) `C_(P)-C_(v)=R` (4) `C_(P)-C_(v)=28R`

A

`C_P-C_V=28R`

B

`C_P-C_V=R//28`

C

`C_P-C_V=R//14`

D

`C_P-C_V=R`

Text Solution

Verified by Experts

The correct Answer is:
B
(b) According to Mayer's relationship `C_P-C_V=R`
`:. (C_P)/M-(C_V)/M=R/M Here M=28`.
