(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A pistol-cylinder device contains 0.8kg of nitrogen initially at 100kPa and 27 degrees C. The nitrogen is compressed in a polytropic process during which PV^1.3 = constant until the volume is reduced by one half. Determine the work done and the heat transfer for this process.

2. Relevant equations

[tex]

W = \int_{1}^{2} {P}dV

[/tex]

[tex]

W_{b} = \Delta U

[/tex]

3. The attempt at a solution

I already figured out the work done, but I can't figure out where the heat transfer comes from.
