  • They contain two or more pure substances:
    mixtures
    renewable materials
    animals
    heterogeneous mixtures
  • In these mixtures, the different substances that form the mixture can be distinguished
    renewable materials
    heterogeneous mixtures
    alloys
    homogeneous mixtures
  • Matter exists in many different forms. We call these forms:
    vegetables
    substances
    animals
    minerals
  • Substances increase in volume when their temperature increases. This is called:
    reflective material
    conductive material
    expansion
    contraction
  • Chocolate milk is an example of a:
    renewable materials
    heterogeneous mixtures
    animals
    mixture
  • mater exists in three different states:
    solid, liquid, and gaseous
  • These include wool, honey, wax, leather and silk
    vegetable
    alloys
    animal
    mineral
  • They are homogeneous mixtures in which one or more component is metal.
    non-renewable materials
    alloys
    heterogeneous mixtures
    renewable materials
  • We can see this type of energy in some natural phenomena such as lightning.
    chemical energy
    electrical energy
    potential energy
    kinetic energy
  • Moving objects have:
    electrical energy
    chemical energy
    kinetic energy
    potential energy
  • In these mixtures, the different components cannot be distinguished
    alloys
    homogeneous mixtures
    renewable materials
    heterogeneous mixtures
  • This energy is stored in substances known as nuclear fuels.
    light energy
    chemical energy
    nuclear energy
    kinetic energy
  • This energy passes from warmer bodies to cooler ones.
    chemical energy
    light energy
    thermal energy
    nuclear energy
  • These include wood, cotton, and rubber
    vegetable
    alloys
    mineral
    animal
  • These include materials such as gold, silver, iron, natural gas and petroleum
    vegetable
    mineral
    non-renewable materials
    animal
  • There are two types of matter:
    pure substances & mixtures
    renewable & non-renewable
    heterogeneous & homogeneous mixtures
    animals & vegetables
  • Oxygen, gold, salt, sugar, and other minerals are:
    pure substances
    renewable materials
    animals
    heterogeneous mixtures
  • They contain only one type of material
    pure substances
    heterogeneous mixtures
    animals
    renewable materials
  • All changes in matter involve:
    energy
  • This is the energy that travels with light. Plants use this energy for photosynthesis.
    kinetic energy
    potential energy
    light energy
    chemical energy
  • Wood, plastic, air, carbon, and diamond are examples of:
    animals
    substances
    minerals
    vegetables
  • The energy an object has due to its position in relation to a force.
    electrical energy
    kinetic energy
    chemical energy
    potential energy
  • These are materials or products that we extract from the natural environment for a particular purpose.
    non-renewable materials
    renewable materials
    primary materials
    heterogeneous mixtures
  • These materials do not run out, because they are produced faster than they are used:
    non-renewable materials
    renewable materials
  • This energy is stored in different substances that during chemical reactions is converted into other forms.
    electrical energy
    potential energy
    chemical energy
    kinetic energy
  • When their temperature decreases, substances decrease in volume.
    conductive material
    expansion
    reflective material
    contraction
  • These materials will eventually run out, because they are used faster than they are produced.
    renewable materials
    non-renewable materials
