`4.48 L` of an ideal gas at `STP` requires 12 cal to raise its temperature by `15^(@)C` at constant volume. The `C_(P)` of the gas is

A

3 cal

B

4 cal

C

7 cal

D

6 cal

Text Solution

Verified by Experts

The correct Answer is:
D
`C_(V)=(DeltaU)/(nDeltaT),n=(4.48)/(2.24)=0.2`
`=(12)/(0.2xx15)=4cal`
`C_(P)=C_(V)+R=4+2=6cal`
