Ques: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. Having read the above passage, choose the right answer to the following question (choices are slower or faster ): When something gets very hot does it move slower or faster?

Ans:faster
