Which one of the following statements is not true about the effect of ...
Distribution of molecular velocities at two different temperature is shown below:-
At higher temperature, moree molecules have higher velocities and less molecules have lower velocities.
From the above figure, it is clear that with the increase in temperature, most probable velocity increases but the fraction of such molecules decreases,
So option c is correct.
At higher temperature, moree molecules have higher velocities and less molecules have lower velocities.
From the above figure, it is clear that with the increase in temperature, most probable velocity increases but the fraction of such molecules decreases,
So option c is correct.

Which one of the following statements is not true about the effect of ...
Effect of Temperature Increase on Distribution of Molecular Speeds in a Gas:
Area under the Distribution Curve:
- When the temperature of a gas is increased, the distribution curve of molecular speeds shifts to higher speeds.
- This shift results in a broader distribution curve.
- However, the area under the distribution curve remains the same as under the lower temperature.
Distribution Becomes Broader:
- An increase in temperature causes the distribution of molecular speeds to become broader.
- This means that a greater range of speeds is observed among the molecules in the gas.
Fraction of Molecules with Most Probable Speed:
- The fraction of molecules with the most probable speed actually decreases with an increase in temperature.
- This is because as the temperature rises, the distribution curve shifts towards higher speeds, reducing the fraction of molecules with the most probable speed.
Most Probable Speed:
- With an increase in temperature, the most probable speed of the molecules in the gas also increases.
- This shift towards higher speeds is a result of the increased kinetic energy of the molecules due to the rise in temperature.
In conclusion, the statement that the fraction of molecules with the most probable speed increases with an increase in temperature is not true. Instead, it actually decreases as the distribution curve shifts towards higher speeds.
