On a TP diagram, two moles of ideal gas perform process AB and CD. If the work done by the gas in the process AB is two times the work done in the process CD, then what is the value of $T_{1} / T_{2}$ ?

Options:

Answer:

Solution:

AB and CD are isothermal: $W = n RT ln \frac{V _{f}}{V _{i}}$ ; the dotted isochores through the origin make $\frac{V _{f}}{V _{i}}$ the same for both.

$\frac{W _{A B}}{W _{C D}} = \frac{T _{1}}{T _{2}} = 2.$
