Physical Properties: These properties can be observed or measured without changing the chemical composition of the substance.
Chemical Properties: These properties describe how a substance reacts with other substances or under certain conditions, resulting in a change in chemical composition.
5 Examples of Physical Properties:
1. Color: The appearance of a substance to the eye. (e.g., red, blue, colorless)
2. Density: The mass of a substance per unit volume. (e.g., 1 g/cm³ for water)
3. Boiling Point: The temperature at which a substance changes from a liquid to a gas. (e.g., 100°C for water)
4. Melting Point: The temperature at which a substance changes from a solid to a liquid. (e.g., 0°C for water)
5. Solubility: The ability of a substance to dissolve in another substance. (e.g., sugar is soluble in water)
5 Examples of Chemical Properties:
1. Flammability: The ability of a substance to burn in the presence of oxygen. (e.g., gasoline is flammable)
2. Reactivity: The tendency of a substance to undergo chemical reactions. (e.g., sodium is highly reactive with water)
3. Corrosion: The gradual deterioration of a substance due to chemical reactions with its environment. (e.g., rusting of iron)
4. Combustibility: The ability of a substance to burn in the presence of oxygen. (e.g., wood is combustible)
5. pH: A measure of the acidity or alkalinity of a substance. (e.g., lemon juice has a low pH, indicating acidity)
