Question

Which statement is not true about increasing temperature and the distribution of molecular speeds in a gas? — Exam MCQ

rrbjepyq.in · Accepted Answer

B. The fraction of molecules at the maximum possible speed increases — Source key: B. On heating, the most probable speed rises, the distribution broadens and its peak lowers, while total area stays constant. The phrase 'maximum possible speed' is imprecise; a Maxwell distribution has no finite maximum speed.
