Question

Maxwell-Boltzmann speed distribution shows that as temperature increases:
  1. A
    Peak shifts to higher speed and distribution broadens
    Correct
  2. B
    Peak stays fixed, only tail grows
  3. C
    Distribution narrows
  4. D
    All molecules acquire same speed

Correct answer

Peak shifts to higher speed and distribution broadens

Explanation

At higher T, the most probable speed v_mp = √(2RT/M) increases, and the distribution broadens because more molecules gain high speeds.
