Basic elements

Great question! Let’s break it down simply:

---

1. Fire

• Made of: Plasma and hot gases (like oxygen, carbon dioxide, water vapor).
• Explanation: Fire is not a solid, liquid, or gas — it's a plasma, which is a state of matter made of ionized gas with free-moving electrons.
• It comes from: A chemical reaction called combustion, when something burns with oxygen.

---

2. Water

• Made of: H₂O — two hydrogen atoms and one oxygen atom.
• Explanation: Water is a compound, formed when hydrogen and oxygen chemically bond.
• It can exist as a liquid, solid (ice), or gas (steam).

3. Gas (Air)

• Made of: A mixture of gases, mainly:
  • Nitrogen (78%)
  • Oxygen (21%)
  • Other gases like carbon dioxide, argon, etc.
• Explanation: Air is not a single substance but a mix of many gases that surround us.

4. Earth (Soil/Rocks)

• Made of: Minerals, organic matter, water, and air.
• Rocks are made of minerals, which are made of elements like silicon, oxygen, aluminum, iron, calcium, etc.
• Soil has broken down rock, plus living things, dead plants, and water.

If you want a fun ancient perspective (like Greek or Islamic philosophy), people used to think these four elements made up everything — and each had its own qualities (hot/cold, wet/dry).

Would you like me to explain that classical view too?
