    Study Notes

    Matter: Properties and Changes

    • Before You Read: Students are asked to consider statements about matter and whether they agree (A) or disagree (D). These statements are then reviewed later in the lesson to see if their views have changed.

    How can a substance's properties be measured?

    • Physical properties: Characteristics observed without changing the substance's identity, such as state, shape, mass, volume, density, solubility, and temperature.

    • Mass: The amount of matter in an object. Mass is constant regardless of location.

    • Weight: The gravitational pull on an object. Weight depends on location; it is greater on Earth than on the Moon.

    Modeling Mass and Volume

    • Mass: Represented by the number of particles, more particles mean more mass. Shown in diagrams of different sized samples.

    • Volume: The amount of space a substance occupies. Measured using graduated cylinders for liquids and by calculating length x width x height for solids with regular shapes. Measured as displacement for irregular shapes. Milliliters (mL) is a common unit for volume.

    Density

    • Density: The mass of a substance divided by its volume. It is a constant for a given substance.

    • Graph: A graph illustrates the relationship between mass and volume, demonstrating that density is consistent unless the substance changes.

    • States of Matter: Solids have the highest density (particles close together). Liquids have lower densities. Gases have the lowest density (particles spread farther apart).

    How can a substance be identified based on how it changes?

    • Chemical Properties: Characteristics observed as a substance changes into a different substance through chemical reactions. Examples:

      • Flammability: The ability to burn easily. (e.g., wood, paper)
      • Oxidation: Reaction with oxygen (e.g., rusting of iron)
      • Reactivity to Acid: Reaction with an acid (e.g., many substances react)

    • Identifying Substances: Physical properties are used to identify substances for example, melting point and density, which do not change, are used to compare against known substances.

    Identifying a Substance Using Properties

    • Physical Properties: Properties used to identify and classify materials:
      • Conductivity: Ability to conduct electricity or heat.
      • Melting/Boiling Point: Temperatures at which a substance changes state.
      • Solubility: Ability of a substance to dissolve in another.
