States of Matter- Chemistry

• Which state of matter has a fixed shape and a fixed volume?

  Solids
• Why can't solids flow?

  Because their particles cannot move from place to place
• Which state of matter have no fixed shape and take the shape of their container easily?

  Liquids
• Which state of matter doesn't have a fixed shape or volume?

  Gases
• What is the process called when liquids turn in to gas

  Evaporation
• What is deposition?


  When gases turn into solid
• What do you call the process when solids turn into gases

  Sublimation
• What is condensation?


  When gases turn into liquid
• Define solute.


  A solid which has been dissolved in a solvent
• Define solvent.


  A liquid in which a solid has been dissolved
• Define solution.


  A mixture in which a solid is dissolved into a solvent
• How can you sped up dissolving?

  Heating the liquid, stirring the liquid and reducing the surface area of the liquid
• What is chromatography?


  A process for separating components of a mixture
• What is a molecule?

  2 or more atoms chemically bonded together
• What is a compound?

  2 or more different atoms chemically bonded together
• Describe saturrated solution.


  A solution in which the maximum amount of solute has been dissolved.
• What's the word for the stationary phase of chromatography?

  Filter paper
• What is the mobile phase of chromatography

  Solvent
• What is simple distillation used for?


  Used to separate a liquid and a soluble solid from a solution.
• What is fractional distillation used for?


  Used to separate two or more liquids that are miscible with one another
• What is filtration used for?


  Used to separate an undissolved solid from a mixture of solid and a liquid.
• What is crystallisation used for?


  Used to seperate an dissolved solid from a mixture of solid and a liquid
• What is paper chromatography used for?


  Used to separate substances that have different solubilities in a given solvent.
