States of matter & mixtures 💦

• What is the structure of solids?

  They are very tightly together.
• What is the movement of solids?

  Vibrations on the spot.
• What is the forces of solids?

  Very strong forces of attraction.
• What is the energy of solids?

  Some kinetic energy.
• What is the structure of liquids?

  Close together.
• What is the movement of liquids?

  Slide over particles but still touching.
• What is the forces of liquids?

  Moderate forces of attraction.
• What is the energy of liquids?

  Moderate kinetic energy.
• What is the structure of gases?

  Far apart.
• What is the movement of gases?

  Fast movement.
• What is the forces of gases?

  Weak forces of attraction.
• What is the energy of gases?

  Lots of kinetic energy.
• What are the properties of solids?

  -Fixed shape.

  -Fixed volume.

  -Cannot be compressed.
• What are the properties of liquids?

  -Can flow.

  -Takes the shape of the container.

  -Cannot be compressed.
• What are the properties of gases?

  -Can flow.

  -No fixed volume or shape.

  -Easy to compress.
• What is freezing?


  Changing state from liquid to solid.
• What is condensing?


  Changing state from gas to liquid.
• What is evaporating?


  Changing state from liquid to gas.
• What is melting?


  Changing state from solid to liquid.
• What is subliming?


  Changing state from solid to gas.
• What is a pure substance?

  A chemically pure substance will have a specific and sharp boiling/melting point and will only include one element or compound type.
• What is an impure substance?

  An impure substance doesn't have the same melting/boiling point and is usually varied or ranged meaning there is more than one type of element/compound type present.
