Answer: temperature only.
- A temperature only
- B molecular mass
- C gas volume
- D gas pressure only
Correct answer: A. temperature only
Explanation: Average translational KE = (3/2)kT, which depends only on absolute temperature.
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.
