  • What is the difference between pure substances and mixtures?
    A pure substance contains only one type of material. A mixture contains two or more types of material.
  • The faster an object is moving, the greater its ______ energy.
    Kinetic
  • Examples of mineral sources include…
    Gold, silver, iron, natural gas, and petroleum.

    Substances
  • What is nuclear energy used for?
    To produce electrical energy in nuclear power plants.
  • What are non-renewable materials?
    Non-renewable materials will eventually run out because they are used faster than they are produced. Examples: Fossil fuels, uranium, and plutonium.
  • What is light energy?
    Energy that travels with light (for example: photosynthesis).
  • What is a substance and give me an example of one.
    Substances are where matter exists. For example: wood, plastics, air, carbon, and diamonds.
  • Give me an example of thermal energy.
