A reversible cycle through which $1\mathrm{.}00$ mol of a

monatomic ideal gas is taken. Volume Vc $=8\mathrm{.}00$Vb$.$

Process bc is an adiabatic expansion, with pb $=10\mathrm{.}0$

atm and Vb $=1\mathrm{.}00103$ m$3.$

a$.$ What is the energy added to the gas as heat,

b$.$ Find the energy leaving the gas as heat,

c$.$ What is the net work done by the gas, and

d$.$ What is the efficiency of the cycle.
