Question

Given is the graph of Maxwell-Boltzmann distribution of molecular velocities.


Which of the option is correct?

• A. $T_1<T_2<T_3$
• B. $T_3<T_2<T_1$
• C. $T_2<T_1<T_3$
• D. $T_2<T_1=T_3$

Answer 1

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

As we know, $u\propto \sqrt{\frac{T}{M}}$
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.
