Consider the isothermal expansion of 4.50 mol of an ideal gas at 450 K from an initial pressure of 12.0 bar to a final pressure of 2.75 bar. Describe the process that will result in the greatest amount of work being done by the system and calculate work Describe the process that will result in the greatest amount of work done by the system with a constant external pressure and calculate w. What is the least amount of work done with no restrictions on the external pressure?
