The figure shows a reversible cycle through which $1\mathrm{.}00$ mole of a monatomic ideal gas is taken. Process $bc$ is an

adiabatic expansion, with $p_b=15\mathrm{.}0$atm and $V_b=1\mathrm{.}10{10}^{-3}{m}^3.$ For the cycle, find $($a$)$ the energy added to the gas as

heat, $($b$)$ the energy leaving the gas as heat, $($c$)$ the net work done by the gas, and $($d$)$ the efficiency of the cycle.
