$-$Part $($a$)$

Write an equation for the efficiency of a heat engine in terms of$$QH$$and the heat$$QC$$exhausted to a low temperature reservoir.$$

$=1-($QC$/$QH$)$Correct$!$

$-$Part $($b$)$

Which would increase the efficiency more, doubling$$QH$$or reducing$$QC$$by half?$$

Doubling Qh$$and reducing Qc$$by half will have the same effect in increasing the efficiency.$$Correct$!$

$$Part $($c$)$

Calculate the maximum thermal efficiency of the power plant.$$

$-$Part $($a$)$

If the initial temperature equals$$T$,$ express the final temperature$$Tf$$in terms of the original temperature$$T$.$

Tf$=3$V$$T$/$V$$Correct$!$

$-$Part $($b$)$

In terms of$$p$$and$$V$,$ calculate the work$$W$$done by the gas.$$

W$=$ p$(3$V$-$V$)$Correct$!$

$$Part $($c$)$

In terms of$$p$$and$$V$,$ calculate the heat$$Q$$flowing into the gas.$$

Q$=$
