Question

The fraction of molecules of a gas possessing velocities in a given range, as given by the Maxwell-Boltzmann distribution, depends on:

• A. Total number of molecules
• B. Temperature
• C. Volume of gas
• D. Pressure of gas

Hint:

Check which variables actually appear in the Maxwell-Boltzmann speed distribution formula.

Answer 1

The Correct Option is B

Curve shape fixed by M,T only. Higher T broadens curve, shifts peak. N only rescales absolute height, not normalized fraction. V,P never enter the formula.

\[\boxed{\text{Temperature}}\]
