Question

Which one of the following statements is NOT true about the effect of an increase in temperature on the distribution of molecular speeds in a gas

• A. The most probable speed increases
• B. The fraction of the molecules with the most probable speed increases
• C. The distribution becomes broader
• D. The area under the distribution curve remains the same as under the lower temperature

Answer 1

The correct option is B The fraction of the molecules with the most probable speed increases

With increase in temprature, fraction of the molecules with the most probable speed decreases.
