Describe the particle arrangement and movement in solids liquids and gases

Solids: the particles are tightly packed together and only vibrate. LIquids: the particles are still a little bit close but are able to move around each other slowly. Gases: the particles a very spread apart and move around really fast.

1 of 9

Suggest the state of a substance when given its properties

Packed tightly together and vibrate: solid. Very spread apart and move really fast: gas a little bit close but are able to move around each other slowly: liquid

2 of 9

Describe the changes of state between solids, liquids and gases

Melting: a solid turning into a liquid by being heated. Evaporating: a liquid turning into a gas by being heated Condensation: a gas turning into a liquid by being cooled

3 of 9

Describe what happens when a solid dissolves in terms of particle arrangement

The particles begin to separate and mix with the liquid’s particles

4 of 9

Explain how to use evaporation to obtain a solid from a solution

You heat the solution so that the liquid will evaporate leaving the solid.

5 of 9

Explain how to use filtration to separate out a solid and a liquid

You pour the solution through a funnel with filter paper in it into a beaker leaving the solid in the funnel and liquid in the beaker.

6 of 9

Explain how to use distillation to separate out two liquids

You heat the mixture to the boiling point of the liquid with the lowest boiling point in a distillation flask which has a water condenser running from it to the beaker. When it gets to the lowest boiling point that liquid will evaporate -

Explain how to use distillation to separate out two liquids

- and go through the water condenser and into the beaker leaving the other liquid in the distillation flask. To get the best results repeat this.

8 of 9

Suggest a suitable method of separating out a given mixture, e.g. sugar and sand.

You mix water with sugar and sand giving you a solution and some sand. Then use filtration which will separate the solution and the sand. Then use evaporation to evaporate the liquid leaving the sugar.
