  • Which gas has the highest average speed at 400K based on molar mass?
    The gas with the lowest molar mass has the highest average speed at 400K.
  • Which of these would have particles with the highest kinetic energy: ice, water, or water vapor?
    Water vapor has particles with the highest kinetic energy.
  • Which contains the particles that are vibrating fastest?
    The sample at the highest temperature contains the fastest vibrating particles.
  • In which phase do particles move most rapidly?
    Particles move most rapidly in the gas phase.
  • What will happen to the gas molecules in the container as thermal energy is applied?
    As thermal energy is applied, gas molecules move faster and their kinetic energy increases.
  • What happens to gas molecules if enough heat is added?
    If enough heat is added, the gas molecules will move faster and may expand or escape the container.
  • Driven by kinetic energy of the molecules, what property of gases is observed?
    Gases expand to fill their containers, driven by the kinetic energy of their molecules.
  • A measure of the average kinetic energy of the particles in a sample of matter is called what?
    Temperature is the measure of average kinetic energy of particles.
  • What state of matter has the most kinetic energy?
    The gas state has the most kinetic energy.
  • At a constant temperature, which of the gases will have the highest average kinetic energy?
    All gases have the same average kinetic energy at a constant temperature.
  • Which statement describes the particles of an ideal gas, based on the kinetic molecular theory?
    Ideal gas particles have negligible volume and no intermolecular forces.
  • For a constant temperature, which will have the greatest average speed?
    The substance with the lowest molar mass will have the greatest average speed at constant temperature.
