Final answer:
Molten lava particles have higher average kinetic energy due to their higher temperature and faster movement.
Explanation:
Molten lava particles would have the greatest average kinetic energy compared to solid rock particles. This is because particles in molten lava are at a higher temperature and are moving faster, leading to greater kinetic energy. The higher the temperature, the more collisions per unit time, influencing the average kinetic energy.
