Ice is a pure substance.
What is a pure substance?
A pure substance is made up of only one type of molecule. Ice is made up only of water molecules (H₂O).
What is ice?
Ice is the solid form of water. It forms when water molecules cool down and slow down, allowing them to bond together in a specific crystalline structure. This structure is what gives ice its unique properties, such as its ability to float on water.
Examples of pure substances:
- Water (H₂O)
- Salt (NaCl)
- Sugar (C₁₂H₂₂O₁₁)
- Gold (Au)
- Oxygen (O₂)
Examples of mixtures:
- Saltwater (a mixture of salt and water)
- Air (a mixture of gases like nitrogen, oxygen, and carbon dioxide)
- Sand (a mixture of different minerals)
