Based on the kinetic-molecular theory, which of the following statements best explains the increase in gas pressure as temperature is increased at a constant volume?

• A. The gas pressure increases as the temperature increases at a constant volume because gas particles exhibit elastic collisions.
• B. The gas pressure increases as the temperature increases at a constant volume because gas particles have kinetic energy proportional to Kelvin temperature.
• C. The gas pressure increases as the temperature increases at a constant volume because gas particles can be compressed without gas molecule interactions.
• D. All of the above
• E. None of the above

Answer: (D)
