A gas undergoes an isothermal process. The specific heat capacity of the gas in the process is:
1. | infinity | 2. | \(0.5\) |
3. | zero | 4. | \(1\) |
Statement I: | \(100\%\) if friction and all dissipative processes are reduced. | The efficiency of any thermodynamic engine can approach
Statement II: | The first law of thermodynamics is applicable only to non-living systems. |
1. | Statement I is incorrect and Statement II is correct. |
2. | Both Statement I and Statement II are correct. |
3. | Both Statement I and Statement II are incorrect. |
4. | Statement I is correct and Statement II is incorrect. |

2. | work done on the system is \(120\) J. |
3. | work done by the system is \(80\) J. |
4. | work done on the system is \(80\) J. |
1. | \(\Delta Q=\Delta U+\Delta W\) |
2. | \(\Delta U=\Delta Q+\Delta W\) |
