Study Notes
Chemical Properties
- Describe the behavior of a substance as it transforms into a new substance.
- Involve a change in the chemical composition of a substance.
- Examples include combustibility and reaction with acid.
Physical Properties
- Attributes that can be observed or measured without changing the substance.
- Qualitative physical properties:
- State: Solid, liquid, gas at room temperature.
- Color: Colorless, red, blue, etc.
- Odor: Sweet, sour, burnt, etc.
- Texture: Crystalline, granular, waxy, flaky, smooth.
- Clarity: Transparent, translucent, opaque.
- Luster: Shininess or dullness of a material.
- Brittleness: Breakability or flexibility.
- Hardness: Ability to scratch or be scratched.
- Malleability: Ability to bend or be shaped.
- Ductility: Ability to be pulled into wires.
- Electrical conductivity: Ability to conduct electricity.
- Solubility: Ability to dissolve in another substance.
- Viscosity: Ability to flow.
- Quantitative physical properties:
- Density: Mass per unit volume.
- Weight: The gravitational force acting on an object.
- Volume: The amount of space an object occupies.
- Melting Point: The temperature at which a solid turns into a liquid.
- Boiling Point: The temperature at which a liquid turns into a gas.
- Freezing Point: The temperature at which a liquid turns into a solid.
