Thermodynamics

[Ashwin]

Can you please help me in this question

 

Nitrogen (molar mass 28kg/kmol) expands reversibly in a perfectly thermally insulated cylinder form 3.5 bar, 200 ^oC to a volume of 0.09m³. If the initial volume occupied was 0.03m³. Calculate the work done during the expansion. Assume Nitrogen to be a perfect gas and take C_V=0.741KJ/KgK

 

Thank you
