The figure illustrates evidence supporting kinetic theory of matter, which describes the behavior of gases based on the motions of the particles. Which claim best describes how evidence in the example supports kinetic theory?

• The balloon gets bigger as the temperature of the gas inside it increases

• The balloon gets bigger as the temperature of the gas inside it increases because the gas particles move faster and get farther apart

• The balloon gets smaller as the temperature of the gas inside it increases

• The balloon gets smaller as the temperature of the gas inside it increases because the gas particles move more slowly and get closer together
