iii. In an isothermal process one mole of an ideal monatomic gas at a temperature T is taken from an initial pressure P; to a final pressure P₁/3. What is the work done during the process in terms of T? State whether the work was done by or on the system. In an isochoric process one mole of an ideal gas of rigid diatomic molecules at volume V taken from an initial temperature T; to a final pressure 4T₁. What is the heat transfer in terms of T;? State whether the heat was absorbed or expelled by the system.
