Question

Gas is compressed slowly and isothermally at 300K from 1 bar to 8 bar. Calculate the work done using the given state of equation. (B = -5.397 X 10-6 m3 /mol) (note: volume at each stage should be near to the ideal gas volume) = 1 + ​

Answer 1

Answer:

Two different steps are used in this case to reach

the same final state of the air. In the first step

the air is heated at a constant volume equal to its

initial valve until the final pressure of 5 bar is

reached. The air temperature at the end of this

step is:

 For this step the volume is constant, and

 During the second step the air is cooled at the

constant pressure of 5 bar to its final state.
