The expansion of unit mass of a perfect gas at constant pressure is shown in the diagram . Here :-

The expansion of unit mass of a perfect gas at constant pressure as shown in the figure, then b and a

The expansion of an ideal gas of mass m at a constant pressure P is given by the straight line D . Then the expanison of the same ideal gas of mass 2m at a pressure P//2 is given by the straight line

The expansion of an ideal gas of mass m at a constant pressure P is given by the straight line D . Then the expanison of the same ideal gas of mass 2m at a pressure P//2 is given by the straight line

The expansion of an ideal gas of mass m at a constant pressure P is given by the straight line B. Then the expansion of the same ideal gas of mass 2 m at a pressure 2P is given by the straight line

The expansion of an ideal gas of mass (m) at a constant pressure (p) is given by the straight line (B) Then, the expansion of the same ideal gas of mass 2 m at a pressure 2 p is given by the straight line. .

The volume-temperature graphs of a given mass of an ideal gas at constant pressure are shown below. What is the correct order of pressure ?
