What are the different states of matter?

Here’s a explanation:

States of Matter

Matter exists mainly in four states, based on particle arrangement and movement:

1. Solid
   • Particles are closely packed and vibrate in place.
   • Has definite shape and volume.
   • Example: Ice, metal, wood.
2. Liquid
   • Particles are close but can slide past each other.
   • Has definite volume but no fixed shape.
   • Example: Water, oil, milk.
3. Gas
   • Particles are far apart and move freely.
   • Has no definite shape or volume, fills the container.
   • Example: Oxygen, carbon dioxide, steam.
4. 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.
