By the law of equipartition of energy, each degree of freedom contributes ___ per molecule:

Answer: (1/2)kT.

A (1/2)kT
B a full kT
C (3/2)kT
D a full 2kT

Correct answer: A. (1/2)kT

Explanation: Each degree of freedom carries an average energy of (1/2)kT.

Not all gas molecules move at the same speed - the Maxwell-Boltzmann distribution shows the spread, with the most probable speed v_p slightly less than the average v_avg, which is slightly less than the root-mean-square speed v_rms used in the pressure formula.

Concept context

Kinetic theory of gases connects molecular motion to pressure and temperature, explaining gas laws, specific heats, and molecular speeds.
