Question

In the following graph of Maxwell-Boltzmann distribution of molecular velocities

Which of the following is the correct order of temperature?

• A. $T_2<T_1<T_3$
• B. $T_1<T_2<T_3$
• C. $T_3<T_2<T_1$
• D. None

Answer 1

The correct option is B $T_1<T_2<T_3$

$u\propto \sqrt{\frac{T}{M}}$
As the temperature is increased, the value of most probable speed increases but fraction of particles possesing most probable speed decreases and the peak of the graph flattens.
