A gas goes from A to B by path 1, doing 100 J of work, and by path 2, doing 250 J of work. The change in internal energy is 300 J. Find the ratio of the molar heat capacities in path 1 to path 2, $\frac{C _{1}}{C _{2}}$ (two decimals).

Answer:

0.73

Solution:

$Q_{1} = 300 + 100 = 400$ J. $Q_{2} = 300 + 250 = 550$ J. Same $n$ and $Δ T$ , so $\frac{C _{1}}{C _{2}} = \frac{Q _{1}}{Q _{2}} = \frac{400}{550} = 0.73$ .
