the molecules that make up a plastic two - liter bottle\na are in constant, rapid, random motion.\nb have a volume of more than two liters if melted.\nc expand to take the shape of wherever the bottle is placed.\nd are closer together than the molecules of soda that they contain.
Answer
Brief Explanations:
According to the kinetic - molecular theory, molecules of any substance (including those in a plastic bottle) are in constant, rapid, random motion. Solids like plastic have a fixed shape and volume, so they don't expand to take the shape of their container like gases, and melting a two - liter plastic bottle won't necessarily result in a volume greater than two liters. Also, the molecules in a solid (plastic) are generally more closely packed than in a liquid (soda), but the key concept here is molecular motion.
Answer:
A. are in constant, rapid, random motion.
