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.
