Ideal gas air is expanded from 600 kPa to 120 kPa while the temperature falls from 400K to 300K. The process is polytropic with PV^n=constant. The initial volume of the air is 0.1m^3 .

1) Find the numerical value of the polytropic component, n.

Solution

The answer of following question is as follows.

The numerical value of polytropic component index is 1.54
