Agas in a piston–cylinder assembly undergoes a process for which the relationship between pressure and volume is pvn = constant. the initial pressure is 1 bar, the initial volume is 0.12 m3, and the final pressure is 9 bar. the value of the polytropic exponent is n = 1.9. determine the final volume, in m3, and the work for the process, in kj.

The final volume is: 0.038 m3 adn the work for the process is: -24.42 KJ

Explanation:

The equation given for a polytropic process when n and C are constants. First we determine the C with the initial conditions:, we need to remember that 1 bar is the same to 100000 Pascals. Then we can calculate the final volume solving the equation given to: so we get:. Now using the integration for work:, replacing data we find the work process like:
