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 the p-T diageam, the AB becomes a part of a hyperbola
D. In going from A to B, the temperature T of the gas decreases

Answer

A, B, D
