Answer: negligible beside.
- A negligible beside
- B much larger than
- C exactly equal to
- D far greater than
Correct answer: A. negligible beside
Explanation: The molecules’ own volume is assumed negligible relative to the space they occupy.
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.
