Air enters an adiabatic nozzle at $300 \mathrm{kPa}, 500 \mathrm{~K}$ with a velocity of $10 \mathrm{~m} / \mathrm{s}$. It leaves the nozzle at $100 \mathrm{kPa}$ with a velocity of $180 \mathrm{~m} / \mathrm{s}$. The inlet area is $80 \mathrm{~cm}^{2}$. The specific heat of air $C_{p}$ is $1008 \mathrm{~J} / \mathrm{kg} . \mathrm{K}$.The exit temperature of the air is
(A) $516 \mathrm{~K}$
(B) $532 \mathrm{~K}$
(C) $484 \mathrm{~K}$
(D) $468 \mathrm{~K}$
