- AIncreases when temperature is increased.
- BDeccreases when temperature is increased.
- CRemains same at all temperature.
- DDepends on the pressure of the gas.
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.
