Answer: kelvin scale.
- A kelvin scale
- B celsius scale
- C fahrenheit scale
- D joule scale
Correct answer: A. kelvin scale
Explanation: Absolute temperature in kelvin is used throughout kinetic theory.
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.
