As shown in the diagram, the state of helium gas is changed in such a way that its PV graph is a straight line segment with volume Vo increases to yVo and pressure Po increases to xPo where x and y are arbitrary constants. During this process the total heat transferred to the gas is equal to the heat necessary to double the absolute temperature of the gas at constant volume. What is the maximum ratio for the volume increase? xP, P. Vo
