Answer: potential energy.
- A kinetic energy
- B rotational energy
- C potential energy
- D thermal energy
Correct answer: C. potential energy
Explanation: Zero interaction between collisions means no intermolecular potential energy in an ideal gas.
Not all gas molecules move at the same speed - the Maxwell-Boltzmann distribution shows the spread, with the most probable speed vp slightly less than the average vavg, which is slightly less than the root-mean-square speed vrms 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.
