A gas fills the entire space of its container, molecules move very fast, and molecules spread out in all directions.

Mass is the amount of stuff inside of something.

A liquid takes the shape of its container, molecules flow past each other, and molecules are loosely arranged.

An odor is a gas made up of molecules.

The three states of matter are solid, liquid, and gas.

In solids, molecules are tightly packed and vibrate in place.

In liquids, molecules are loosely arranged and can flow past each other.

In gases, molecules are far apart, move very fast, and fill the entire space of their container.

Mass is the amount of matter in an object, while volume is the amount of space that object occupies.

The molecules gain energy, move apart, and begin to flow past each other.
