question: Rich is examining a cold particle and a hot particle. Which likely moves the fastest?
choices.text: the hot particle the cold particle
choices.label: A B
para: At higher temperatures, particles of reactants have more energy, so they move faster. They are more likely to bump into one another and to collide with greater force.
para_anno.effect_prop: movement speed
