Which one of the following statement is not true about the effect of an increase in temperature on the distribution of molecular speed?

Options

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

B

Explanation

According to Maxwell.s distribution, the most probable velocity increases as the fraction of molecules possessing most probable velocity decreases.
