Question

In the following graph of Maxwell-Boltzmann distribution of molecular velocities. Which of the following is the correct order of temperature?

• A. $\text{T}_{1} < \text{T}_{2} < \text{T}_{3}$
• B. $\text{T}_{3} < \text{T}_{2} < \text{T}_{1}$
• C. $\text{T}_{2} < \text{T}_{1} < \text{T}_{3}$
• D. None of these

Answer 1

Answer: (A)

The peak represents U_MPS as $\text{U}_{\text{M} \text{P} \text{S}} \propto \sqrt{\text{T}}$ , the graph a T₃ has maximum U_MPS, hence T₃ is the highest temperature.
