An ideal gas is taken from the state A (pressure P, volume V) to the state B (pressure `p//2`, volume 2V) along a straight line path in the P-V diagram. Select the correct statement (s) from the following :

Options

A. The work done by the gas in the process
A to B exceeds the work that would be done by it if the system were taken from A to B along an isotherm
B. In the T–V diagram, the path AB becomes a part of a parabola
C. In going from A to B, the temperature T of the gas first increases to a maximum value and then decreases
D. All of these

Answer

D
