2.4 kg of nitrogen at an initial state of 285k and 150 kpa is compressed slowly in an isothermal process to a final pressure of 600 kpa. determine the work.

W=-280.67 KJ

Explanation:

Given that

Initial pressure = 150 KPa

Final pressure = 600 KPa

Temperature T= 285 K

Mass m=2.4 Kg

We know that ,work in isothermal process given as

Gas constant for nitrogen gas R=0.296 KJ/kgK

Now by putting the values

W=-280.67 KJ

Negative sign indicates that it is compression process and work is done on the gas.
