Kinetic particle model of matter — practice question

A set quantity of gas is enclosed in a metal can. The gas temperature falls, but its volume stays constant. How does this alteration affect the kinetic energy of the gas molecules and the pressure in the metal can?

  • Akinetic energy decreases; pressure decreases
  • Bkinetic energy decreases; pressure increases
  • Ckinetic energy increases; pressure decreases
  • Dkinetic energy stays the same; pressure decreases
