Midterm $2$

$1.$ A frictionless piston$-$cylinder device initially contains $\backslash (1\mathrm{.}2\backslash$mathrm$\{$~m$\}^\{3\}\backslash )$ of oxygen gas at a temperature of $150$ K and pressure of $120$ kPa $.$ Heat is now transferred to the oxygen gas in the device. At the end of the process, the volume of the oxygen gas is tripled. Assume that the oxygen gas is an ideal gas with constant specific heats, and its specific heat values can be evaluated at the temperature of $300$ K $.$ Determine the amount of heat that is transferred to the oxygen gas during the process.
