11/6/24 PhET States of Matter Basics

The state of matter in which the atoms are close together but not always touching.

• liquid

• solid

• gas

Answer explanation

In a liquid state, atoms are close together but can move past one another, allowing them to not always be in contact. This distinguishes liquids from solids, where atoms are tightly packed and fixed in place, and gases, where atoms are far apart.

The state in which atoms are loosely packed and tend to completely fill the container.

• liquid

• solid

• gas

Answer explanation

In a gas, atoms are loosely packed and move freely, allowing them to completely fill their container. This distinguishes gases from liquids and solids, where atoms are more closely packed and do not fill the container completely.

The state in which atoms are tightly packed and tend to keep their shape.

• liquid

• solid

• gas

Answer explanation

Atoms in a solid are tightly packed, allowing them to maintain a fixed shape. In contrast, liquids and gases have more space between atoms, which prevents them from keeping a defined shape.
