| Definition |
| Matter can be defined as a substances that has mass and occupies space. |
Physical Properties of Matter
| Definition |
|
Physical properties are the properties that can be identified by using our five senses or measuring tools
|
Examples of physical properties:
- Hardness
- Colour
- Odour
- Solubility
- Melting, freezing and boiling points
Chemical Properties of Matter
| Definition |
|
Chemical properties are the properties of a substance that become evident when it changes to a new substance.
|
Examples of chemical properties:
- Rusting
- Flammability
- Oxidation
| Characteristics |
| Density |
- The ability of a material to float or sink in water.
- A material that has a lower density will float
- A material that has a higher density will sink.
|
| Melting Point and Boiling Point |
- Melting point is the temperature at which a substance changes from solid to liquid.
- Boiling point is the temperature at which a substance changes from liquid to gas
- Melting point water: \(0^\circ{\text{C}}\)
- Boiling point water: \(100^\circ{\text{C}}\)
|
| Solubility |
- Ability of a substance to dissolve in given amount of solvent to form a solution.
- The solubility of a substance depends on the physical and chemical properties of its solute and solvent
