The volume versus temperature graph of two moles of helium gas is shown in Figure 3.79 (a straight line through the origin). The ratio of heat absorbed and the work done by the gas in process 1-2 is:

Options:

Answer:

Solution:

$V \propto T$ means constant pressure. $Q = n C_{p} Δ T = n \frac{5}{2} R Δ T$ and $W = n R Δ T$ . $\frac{Q}{W} = \frac{5}{2}$ . B.
