MCQ
In Maxwell's velocity distribution curve area under the graph:
- AIncreases when temperature is increased.
- BDeccreases when temperature is increased.
- CRemains same at all temperature.
- DDepends on the pressure of the gas.
✓
Answer
- Remains same at all temperature.
Explanation:
Area under the Maxwell's velocity distribution curve gives the number of particles. Since number of particles remains the same at all the temperatures, so the area under the curve also remains the same at all temperature.
