Questions and Answers

What is a physical property?

  • A property related to chemical reactions
  • A property that can be tested without changing the substance (correct)
  • A property that changes the substance
  • A property only observed in solid substances

    • What is a chemical property?

  • A property that can be tested without changing the substance
  • A property related to physical changes
  • A property that is tested and changes the substance (correct)
  • A property that remains the same during testing

    • What is a physical change?

    A change in an object where the substance remains the same.

    Study Notes

    Physical and Chemical Properties

    • Physical properties can be tested without changing the substance's identity.
    • Chemical properties require a change in the substance to be observed.

    Physical and Chemical Changes

    • Physical changes alter the form of a substance without changing its composition (e.g., tearing paper).
    • Chemical changes result in the formation of new substances through reactions (e.g., mixing chemicals).

    Distinguishing Properties and Changes

    • Properties are characteristics of a substance (e.g., color, mass).
    • Changes refer to transformations that modify the substance itself (e.g., cooking food).

    Examples of Physical Properties

    • Color
    • Smell
    • Volume
    • Mass
    • Density

    Examples of Chemical Properties

    • Reactivity with oxygen
    • Flammability
    • Heat reactivity

    Examples of Physical Changes

    • Tearing a piece of paper
    • Chewing food
    • Sharpening a pencil

    Examples of Chemical Changes

    • Mixing two substances to create a new one
    • Digesting food
    • Decomposition processes
    • Burning materials
    • Cooking food

    Key Physical Properties Definitions

    • Viscosity: Measurement of a liquid's resistance to flow.
    • Density: Mass per unit volume of a substance.
    • Electrical Conductivity: Ability of a substance to conduct an electrical current.
    • Thermal Conductivity: Rate at which a substance transfers heat.

    Substance States and Characteristics

    • State/Phase: The physical form in which a substance exists (solid, liquid, gas).
    • Solubility: Capacity of a substance to dissolve in another.
    • Ductility: Ability to be drawn into wires.
    • Malleability: Ability to be rolled into thin sheets (e.g., tin foil).
    • Surface Tension: Force acting on the surface particles of a liquid.
