Study Notes
Physical Properties
- Observed and measured without altering the substance's identity.
- Examples include melt point, boil point, density, hardness, and solubility.
- Key indicators include texture (surface feel) and color (not a definitive identifier).
Chemical Properties
- Only observed during chemical reactions when substances interact, resulting in a new substance.
- Examples encompass flammability, oxidation, and toxicity.
- Reactivity to water and radioactivity are also notable chemical properties, indicating how a substance may behave in different environments.
Specific Terms
- Solubility: Determines if a substance can dissolve in water.
- Hardness: Measures the softness or firmness of a material.
- Thermal Conductivity: Assesses how well heat passes through a substance.
- Electrical Conductivity: Indicates a material's ability to conduct electricity.
- Magnetism: Relates to the attraction of matter to magnets.
- Melting Point: Temperature transition from solid to liquid.
- Boiling Point: Temperature at which a liquid becomes a gas.
- Density: Ratio of mass to volume, fundamental for material identification.
- Odor: The scent emitted by a substance affecting olfactory receptors.
- Toxicity: Concerns the harmful effects of a substance.
- Flammability: Capacity of a material to ignite and combust.
- Oxidation: Reaction with oxygen, often leading to rusting.
- Reactivity to Water: Interaction tendency when in contact with water.
- Radioactivity: Emission of radioactive particles from unstable nuclei.
- Chemical Stability: The tendency to maintain the same chemical composition over time.
