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.
- The workdone 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 the isotherm.
- In the T-V diagram, the path AB becomes a part of a parabola.
- In the P-T diagram, the path AB becomes a part of a hyperbola.
- In going from A to B, the temperature T of the gas first increases to a maximum value and then decreases.
Answer
(D) In going from A to B , the temperature T of the gas first increases to a maximum value and then decreases.
