Heat and Thermal ExpansionHard

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 : -

Options

A.> 1
B.< 1
C.1
D.Data insufficient

Solution

Q1 = ᐃU + W1 ; Q2 = ᐃU + W2
Ratio of specific heats
< 1 (∵W2 > W1)
