Current Attempt in Progress

Air contained in a rigid, insulated tank fitted with a paddle wheel, initially at $300K,\frac{2}{b}ar,$ and a volume of $2m^3,$ is stirred until its temperature is $500$ K $.$

Assuming the ideal gas model for the air, and ignoring kinetic and potential energy, determine :

$($a$)$ the final pressure, in bar.

$($b$)$ the work, in kJ$.$

$($c$)$ the amount of entropy produced, in $k\frac{J}{K}.$

Solve using:

$(1)$ data from Table A$-22.$

$(2)$ constant $c_v$ read from Table A$-20$ at $400$ K $.$
