Q 2(c) The pressure-volume diagram to the right shows an isothermal expansion process for 2.20 moles of an ideal gas at 355 K from 0.200 m3 to 0.500 m3. (i) Show that the work done in the isothermal process shown to the right is given by: W = nRT[ln(V2) − ln(V1)] (ii) Calculate the work done in the isothermal process. [2 Marks] Volume
