Liquid Oxygen Reading Questions Amplify Phase Change

Front

What is molecular attraction?

Back

The force that pulls molecules of the same substance together.

Front

Why do the molecules of liquids and solids stay together?

Back

The level of attraction between molecules of these phases is greater than their kinetic energy.

What happens to a liquid when there is a large increase in kinetic energy?

Back

It becomes a gas, because kinetic energy makes molecules able to spread further apart.

What is the difference between solids, liquids, and gases in terms of molecular arrangement?

Back

Solids have closely packed molecules, liquids have loosely packed molecules, and gases have widely spaced molecules.
