If `C_p, bar(C )` and C of `CO_2` gas are equal at `T_1 ,T_2 and T_3` temperatures then 

A

`T_1 lt T_2 lt T_3`

B

`T_1 gt T_2 gt T_3`

C

`T_3 gt T_1 gt T_2`

D

`T_1 = T_2 = T_3`

Text Solution

Verified by Experts

The correct Answer is:
B
Velocities `alpha sqrt(T)`
normally at same `T, C_p < C`
but as `T uarr, C_p = C_((T)) implies T_1 > T_2`
Similarly `T_2 > T_3`.
