50 R calories of heat is required to raise the temperature of 4 moles of an ideal gas at constant pressure from `50^@`C to `55 ^@` C. The gas may be :

A

`N_2`

B

`CO_2`

C

He

D

`CH_4`

Text Solution

Verified by Experts

The correct Answer is:
B
dQ =` nC_pdT`
`C_p = (dQ)/(ndt) = (50R)/(4 xx 5) = 5/2 R ``implies` monoatomic
