Under the isothermal condition, a gas at \(300 \mathrm{~K}\) expands from \(0.1 \mathrm{~L}\) to \(0.25 \mathrm{~L}\) against a constant external pressure of 2 bar. The work done by the gas is:
| 1. | \(30 ~\mathrm {J} \) | 2. | \(-30 ~\mathrm{J} \) |
| 3. | \(5~ \mathrm{kJ}\) | 4. | \(25~ \mathrm{J}\) |
