Calculate the work necessary to isothermally perform steady compression of 2 moles of an ideal gas from 1 bar to 10 bar and 311K in a piston. An isothermal process is one at constant Temperature. The steady compression of the gas should be performed such that the pressure of the system is always practically equal to the external pressure on the system. This is referred to as reversible compression.
