 * **Solid=** A object that has shape and volume and is not liquid or gaseous.
 * **Liquid=** A substance that is able to flow and and that can apear when something has happened to a solid object.
 * **Gas=** A substance that is gaseous that can be caused by a change of a abiotic factor that can make a solid or liquid turn into a gas.
 * **Particle=** A section/part or portion of an object.
 * **Compress=** To make something compacted by pressing it together to make it smaller in size.
 * **Expand=** To increaset eh size, volume or quantity of an object.
 * **Condensation=** The act of condensing an object or the state of being condensed in some way.
 * **Freezing=**When a liquid has been changed to a solid and is cold in temperature.
 * **Melting=** When the sate of a solid is changing to a liquid by heating.
 * **Evaporation=** When a liquid is changing to the state of vapour by additon of heat.
 * **Sublimation=** It is the act of changing a solid to a gas without it turning into a liquid before hand.

Describing the diagrams....

This diagram shows that in different objects the particles that make it form are layed out differently. In gas the particles are spread out and are not touching but ina ny liquid substance the particles in that are spread out but are touching in some way. The similarities and differences between gas and any liquid is that the particles are all spread out which is common in both types of objects but the difference is that in gas they are not touching and in any other liquid substance they are touching in some way or another. Then there is the solid objects that are mae up by lots of particles and they all are touching. I think the particles are different in these different substances because a solid is firm and hard. A liquid is a substance that is joined by the particles. E.G If you pour a glass of water a spill of it comes out not just one drop. This is becasue water is not a substance that has lots of little things everywhere it has many particles that are connencted. A gas is totally different substance as in gas the particles are not connected because of how it is formed and how the particules connect together.

These three substances are all different because they also feel different by touch. A solid object feels hard and you can see any solid object. A liquid can sometimes have a different temperature. A liquid can either be runny or slimey becasue of what it is made of and how it is looked after. A gas can sometimes not be seen by the naked eye and will probably can sometimes not even be smelt, heard or touched depending on the type of gas it is and what it does.

Answering Questions from ** []


 * What is sublimation?**

Sublimation is the state of a solid going to the sate of gas/vapour with out passing through the step of becoming a liquid. Normally as you increase the heat of a solid for example ice it first turns into water and then as you move higher in temperature it finally turns into a gas (water vapour). This all happens because as you increase the temperature of the ice you are adding more energy to it which make the particles in it move around more. This changes the state of the solid to a liquid or gas.


 * Supposing you increased the pressure of the air above the boiling liquid. What would happen to the boiling point of the water?**

The boiling point would have to be increased to allow the particles to have enough heat/energy to be able to get out and not be pressurised. To make the particles have enough energy the temperature also needs to be increased. If the pressure was increased it means that your boiling point has to be higher as the boiling point is the temperature at which the liquid turns into a gas (water vapour).


 * Imagine that you are trying to boil water for a cup of tea up a mountain. Why would the cup of tea be fairly horrible?**

The cup of tea wouldn't be that pleasant as the low pressure at the top of the mountain would cause the boiling point of the water in to cup of tea would have to be lower and the cup of tea wouldn't be as nice as it would be colder in temperature.


 * Does water contract or expand when changing from a liquid to a solid?**

Water expands when it freezes and it the only known substance that scientists know of that actually expands when freezing. This is because the particles inside the water rearrange while they are freezing. All other liquid substances compact as the change of the arrangement in the particles gets smaller. For example:

Inside a liquid the particles are compact but they still have some energy which allows them to move around. But in a solid the particles are totally compact which means if you change a liquid to a solid the particles would compress which make the solid smaller.
