# Pressure versus Temperature graph of an ideal gas is shown below. Then which of the options that follow forms the corresponding P-V Diagram?

Options:

(A) $\quad$ (B)

(C) $\quad$ (D)

For an ideal gas, PV = nRT.
From A to B, pressure varies linearly with temperature $\rightarrow$ volume must be constant.
From B to C, temperature is constant with decreasing pressure, so its an isothermal expansion.
For C to A, presure is constant and temperature is decreasing, and so is volume.
So, the PV diagram looks like this:
