Question

2) Calculate w for the adiabatic expansion of 2.50 mol of an ideal gas at an initial pressure of 2.25 bar from an initial temper- ature of 450. K to a final temperature of 300. K. Write an expression for the work done in the isothermal reversible expan- sion of the gas at 300. K from an initial pressure of 2.25 bar. What value of the final pressure would give the same value of w as the first part of this problem? ,m
