The Carnot cycle (reversible) of gas is represented by a pressure-volume curve as shown in the figure. Consider the following statements:
I. | The area \(ABCD\) = The work done on the gas |
II. | The area \(ABCD\) = The net heat absorbed |
III. | The change in the internal energy in the cycle = \(0\) |
Which of the statement(s) given above is/are correct?
1. | I only | 2. | II only |
3. | II and III | 4. | I, II, and III |
1. | The change in internal energy in the process \(BC\) is \(-500R.\) |
2. | The change in internal energy in the whole cyclic process is \(250R.\) |
3. | The change in internal energy in the process \(CA\) is \(700R.\) |
4. | The change in internal energy in the process \(AB\) is \(-350R.\) |
1. | The magnitude of the work done by the gas is \(RT_{0}\ln 2.\) |
2. | The work done by the gas is \(V_{0}T_{0}.\) |
3. | The net work done by the gas is zero. |
4. | The work done by the gas is \(2RT_{0}\ln2.\) |
