Study Notes
Changes to Substances
- A substance can undergo two types of changes: reversible and irreversible changes.
Reversible Changes
- A substance can return to its original state.
- The chemical properties of the substance do not change.
- Most physical changes are reversible changes.
- No new substances are formed.
Irreversible Changes
- A substance cannot return to its original state.
- The chemical properties of the substance change.
- All chemical changes are irreversible changes.
- New substances are formed.
Key Concepts
- Melt: a type of physical change.
- Evaporate: a type of physical change.
- Solution: a mixture of a solvent and a solute.
- Solvent: the substance that dissolves the solute.
- Solute: the substance that is dissolved in the solvent.
- Uniform: a mixture that has the same composition throughout.
- Condense: a type of physical change.
