2 moles of a gas with ideal behavior are compressed isothermally at a temperature of 25 °C in a reversible way by passing from a initial volume of 1 l (V1) to a final volume of 0.5 l (V2). Subsequently the gas is made to expand reversibly until it returns to the initial volume through an isobaric expansion and subsequently yes returns to the initial temperature via an isochore. Compare the work put into play in the two cases.
