To understand the states of matter, we can look at three main types: solid, liquid, and gas. Each one has unique features that make it special.

Solid:

• Shape and Volume: Solids keep their shape and size. They don’t change form easily.
• Particle Arrangement: The tiny parts, or particles, in solids are packed tightly together, which makes them strong and hard.

Liquid:

• Shape and Volume: Liquids have a set size but change shape based on the container they’re in. They can flow and move around to fill the space.
• Particle Arrangement: The particles in liquids are close together but can slide past each other. This is why liquids can flow easily.

Gas:

• Shape and Volume: Gases don’t have a fixed shape or size. They spread out to fill any space they’re in.
• Particle Arrangement: The particles in gases are spread far apart and move freely. This makes gases less dense and easy to compress.

Knowing these differences helps us see how matter acts and changes in different situations!
