56 - What is the difference between a solid, liquid, and gas?

Imagine the tiny particles that make up everything around us.

• Solids: In solids, the particles are closely packed and don't move much. They stay in the same place. Examples: rocks, toys, and tables.
• Liquids: In liquids, the particles are close but can move around each other. They can flow. Examples: water, oil, and juice.
• Gases: In gases, the particles are really far apart and can move freely. They spread out and can fill a room. Examples: air, helium in balloons, and the vapor that comes out when you take a hot shower.

These are the three main states of matter.
