A thermodynamic system undergoes a cyclic process \(ABCDA\) as shown in Fig. The work done by the system in the cycle is:
1.
2.
3.
4. Zero
1. | \(1000~\text{J}\) | 2. | zero |
3. | \(-2000~\text{J}\) | 4. | \(2000~\text{J}\) |
In the cyclic process shown in the pressure-volume \((P-V)\) diagram, the change in internal energy is equal to:
1.
2.
3.
4. zero
ABCA is a cyclic process. Its P-V graph would be:
1. | 2. | ||
3. | 4. |
For the indicator diagram given below, which of the following is not correct?
1. | Cycle - II is a heat engine cycle. |
2. | Net work is done on the gas in cycle I. |
3. | Work done is positive for cycle I. |
4. | Work done is positive for cycle II. |
In the P-V diagram shown, the gas does 5 J of work in the isothermal process ab and 4 J in the adiabatic process bc. What will be the change in internal energy of the gas in the straight path from c to a?
1. 9J
2. 1 J
3. 4 J
4. 5 J
In a cyclic process, the internal energy of the gas:
1. | Increases | 2. | Decreases |
3. | Remains constant | 4. | Becomes zero |
