Vedclass · Answer

(B) As the temperature of a gas increases,the Maxwell-Boltzmann distribution curve shifts to the right and flattens.$1$. The most probable speed $(v_{mp} = \sqrt{2RT/M})$ increases.$2$. The peak of the curve shifts to the right and its height decreases,meaning the fraction of molecules possessing the most probable speed decreases.$3$. The distribution curve becomes broader.$4$. The total area under the curve represents the total number of molecules,which remains constant regardless of temperature.Therefore,the statement that the fraction of molecules with the most probable speed increases is $NOT$ true.

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?
