Here’s a explanation:
States of Matter
Matter exists mainly in four states, based on particle arrangement and movement:
- Solid
- Particles are closely packed and vibrate in place.
- Has definite shape and volume.
- Example: Ice, metal, wood.
- Liquid
- Particles are close but can slide past each other.
- Has definite volume but no fixed shape.
- Example: Water, oil, milk.
- Gas
- Particles are far apart and move freely.
- Has no definite shape or volume, fills the container.
- Example: Oxygen, carbon dioxide, steam.
- Plasma
- Ionized gas with free electrons and ions.
- Conducts electricity and responds to magnetic fields.
- Example: Stars, neon signs, lightning.
Key Idea:
- Solids → Liquids → Gases → Plasma = increasing particle energy and movement.
In short: Matter exists as solid, liquid, gas, and plasma, depending on particle arrangement and energy.
