My Definitions My photos and diagrams Describing the photos and diagrams

DEFINITIONS:

Solids: A firm and stable shape that is not a liquid or fluid. Liquid: A substance that flows freely but of constant volume. Gas: A substance that s airy and can be caused by Particle: A small amount, piece or fragment, a tiny or very small piece of something. Compress: To press together or to force into small space. Expand: To increase or extend in size, volume or quantity of an object. Condensation:

Describing the diagram: This diagram shows the particles in some different forms. THe particles in each are layed out diferently. In the solids, the objects that are made up by lots of little particles and are all stuck together and touching. I recon the particles are all touching and squashed together is to show that the solid is firm and hard. These particles are different as they are different substances. The Gas particles are all spreadded out in this diagram. THey are not touching and are spread apart from each other, but in any other liquid substance all the particles are spread out but are all still touching each other in a way. The differences and similarities between the gas and liquid is that the particles are both spread out which is normal in both objects but the differences are that the gas is not touching any other particles and yet the liquid is touching other particles. A liquid is a substance where all particles are joined together. So if you try to pur a liquid substance you cant just pour one particle, it all comes out as all particles together. This is cause water has many particles connected to each other. Now gas is a totally different subsatnce to liquid and a solid as it doesnt touch other particles and they are apart from each other. The particles are not connected as they are parted and not touching.

All these different 3 substances are all quite different to each other as they all feel connected and touched by particles. Gas cant be seen with the naked eye but still can be smelt by human. Can can be heard only if a gas tap is leaking or have been exposed. It may be touched depending on the type of gas and chemicals. A solid object is hard and can be seen. A liquid can have different smells, feels, tastes and also different tempretaures depending on what the liquid is. A liquid can be hard and also very thin in different cases. Depends on the chemicals and types of liquids are put in there.

Changing Matter Questions: When you put pressure on the boiling liquid it would put pressaure on the particles in the boiling water and would make it harder for the particles inside to try to escape to make a gas, so the boiling point up on a mountain would be low as it is up high and would have a low boiling point. So the tea would need hot boiling water for the tea bag mixtaure would seem and mix into the water but that ccant do that unless there is boiling water, if your up high on a mountain the boiling point is colder so the tea bag wouldnt seep in as the water is cold and not at a boiling point.
 * 1) What is sublimation?
 * 2) Supposing you increase the pressure of the air above the boiling liquid. What would happen to the boiling point of water?
 * 1) Imaging that you are trying to boil a cup of water for a cup of tea up a mountain. Why would the cup of tea be fairly horrible?
 * 2) Does water contract or expand on changing to a liquid to a solid?
