🧪 States & Properties of Matter

  • Liquid: Definite volume but no definite shape.

  • Gas: No definite volume or shape.

  • Gas Volume and Temperature: Volume increases as temperature rises.

  • Solubility: Physical property describing a substance's ability to dissolve.

  • Water State Change: Liquid water boils to form water vapor.

⚗ Chemical & Physical Changes

  • Physical Change: Alters form or shape without changing chemical makeup.

  • Non-State Physical Change: Crushing or breaking an object with a hammer.

  • Chemical Change: Forms entirely new and different substances.

  • Compound: Substance made of two or more chemically combined atom types.

  • Conservation of Mass: Mass remains completely identical during state changes.

  • Closed System Mass: Total mass stays exactly the same during gas-producing reactions.

🌪 Mixtures, Solutions & Separations

  • Solution: Uniform mixture with the same composition throughout.

  • Oil and Water Separation: Letting oil float to the top to skim it off.

  • Steel Alloy Properties: Formulated to be strong and slightly flexible.

  • Dissolving Rate Factors: Affected by temperature, particle size, and stirring speed.

  • Irrelevant Dissolving Factor:
