Rita has two small containers, one holding a liquid and one holding a gas. Rita transfers the substances to two larger containers. Compare the behavior of the atoms in the liquid and in the gas once they are moved to the larger containers.

Answer:

Liquids and gases are similar because they both take the shape of the container they are in. However, they are different because liquids have a definite volume, while gases do not and will expand to fill any available space. This is because the atoms in a gas move more freely than those in a liquid.
