a$)$ Determine T$,$ P$,$ and V at each

point $($a$,$ b$,$ c$,$ d$).$

b$)$ Determine W$,$ Q$,$ and $$U for

each step $($a $$ b$,$ etc.$).$

c$)$ Determine the net work done by the gas.

d$)$ Determine the net heat added to the gas $($total heat added $$ total heat taken away from gas$).$

e$)$ Determine the efficiency of this cycle. $=$ net work

total heat added $,$ but note here that $$total heat

added$$ does not include heat expelled. It only includes heat that is added to the system

$($not taken away$).$
