Answer: temperature.
- A temperature
- B the pressure
- C the volume
- D the shape
Correct answer: A. temperature
Explanation: For an ideal gas, internal energy is a function of temperature alone.
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.
