Why do gases expand to fill the shape of their container?

• The particles in a gas are tightly packed together.
  

• Gas particles are fixed in one position and cannot move.

• Gas particles move freely and have a lot of space between them.

• The particles in a gas are compressed into a smaller volume.

If you heat a solid until it melts into a liquid, what happens to the particles?

• The particles stop moving and stay in one position.
  

• The particles move more freely and slide past each other.

• The particles move farther apart and stop interacting.

• The particles vibrate in place and become more tightly packed.
