Matter

  • Matter
    The name given to all substances. To be called this, something must have mass and volume.
  • Mass
    Measured in kg and is the amount of matter something has.
  • Volume
    How much space the substance takes up and is normally measured in litres.
  • Solids
    Have a fixed shape that cannot be easily changed, and cannot be easily compressed.
  • Liquids
    Changes shape to fill its container, has a fixed volume and is difficult to compress.
  • Label which containers contain solids, liquids or gasses.
    A) Gas
    B) Liquid
    C) Solid
  • Fluid
    A substance that can flow, be it a liquid or gas
  • Weight and mass are commonly confused. Mass is how heavy a substance is, however weight is mass multiplied by gravity, thus is measured in newtons. Scales factor out gravity, therefore when you use a scale you are actually measuring your mass, not your weight.
  • Viscosity
    How quickly a liquid flows. If it is high it will flow slowly, while if it is low the liquids will flow freely.
  • Water is the only substance on Earth that exists in three different states at normal temperatures.
  • Deposition
    Very rare change of state of matter, where a gas turns straight to a solid, skipping the liquid phase.
  • Sublimation
    Very rare change of state of matter, where a solid turns straight to a gas, skipping the liquid phase.
  • The melting point and freezing point of water is 0 degrees celcuis.
  • The boiling point and condensing point of water is 100 degrees.
  • Particle Model
    All substances are made from particles, particles are attracted to other particles, particles are always moving and the hotter the substance is the more particles move.
  • Movement of Particles in Solids
    The particles are very close together and cannot be compressed. The attraction between particles is very strong, and the particles don't move freely. Instead, they vibrate in place. Solids generally have a fixed shape and volume.
  • Movement of Particles in Liquids.
    Liquids have weaker particle attraction and have more kinetic energy than solids, allowing them to roll over each other but not escape. They can conform to the shape of the container they are in, and have a fixed volume. They cannot be compressed
  • Movement of Particles in Gases
    The particles have much more energy than solids or liquids, meaning they almost completely overcome the force of attraction. They always spread out to take up all the space they have, thus can be compressed and have no fixed shape or volume. They are also constantly moving.
  • Gasses
    Spreads out and will not stay in a container unless it has a lid, thus diffuses into all of the available space. It has no fixed shape and can be compressed with little difficulty.
  • Mass
    How much matter is in a substance.
