There are two samples A and B, which contains two different gases. Each sample has one mole of a gas. Graph between internal energy (E) and temperature (T) as shown in figure, then:

A

A contains He, B contains `N_2`

B

B contains `N_2`, A contains `O_2`

C

A contains `CO_2`, B contains He

D

A contains He, B contains `CO_2`

Text Solution

Verified by Experts

The correct Answer is:
C
`E = f/2 RT` for 1 mole when f is degree of freedom. Slop `= (fR)/2` is greater for A `rArr f_A gt f_B`
