Question

Maxwell"s velocity distribution curve is given for the same quantity for two different temperatures. For the given curves then which of the folowing relation is true?

• A. $T_1>T_2$
• B. $T_1<T_2$
• C. $T_1\le T_2$
• D. $T_1=T_2$

Answer 1

The correct option is B $T_1<T_2$

Most probable velocity $v_{mp}=\sqrt{\frac{2kT}{m}}$
As T increases $v_{mp}$ increases.
$(v_{mp}{)}_{T_2}>(v_{mp}{)}_{T_1}$
$\Rightarrow T_2>T_1$
$\Rightarrow T_1<T_2$
