Question

The figure shows two paths for the change of state of a gas from A to B. The ratio of molar heat capacities in path 1 and path 2 is

A. `gt1`
B. `lt1`
C. `1`
D. data insufficient

Answer 1

Correct Answer - B
Molar heat capacity `C=(DeltaQ)/(DeltaT)`
or `C=(DeltaU+DeltaW)/(dT)`
`DeltaU` is same in both the paths but `DeltaW_(2)gtDeltaW_(1)`
`:. C_(2)gtC_(1) or (C_(1))/(C_(2))lt1`.
