__Definitions:__
**Solid: Solid has a definite shape and volume. It is not hollow and it is in a solid form that cannot be spilt. You can feel the three dimensions (length, breadth, and width) with your bare hand. Liquid: Liquid has a definite volume and takes the shape of the container it is in. It's form is wet and is like fluid. Gas: Gas fills the whole volume of the container. The form of gas cannot be seen by the naked eye. Particles: Particles are small parts or a chemical substance. Boiling Point: Boiling point is the hottest a chemical substance can ever get. On a thermometer it is 100 degrees celsius. Freezing Point:** Freezing point is the coldest chemical substance can ever get. On a thermometer it it 0 degrees celsius. **Sublimation:** Its when a solid changes to a gas without turning into liquid.
 * Phase:** A phase is a form is a form of matter. Eg solid, liquid, and gas.

__Diagrams:__
=== === ===Diagram 1:  This diagram shows an example of three phases: gas, liquid, and solid. The phase  gas  shows that the particles move freely but do not connect together. The phase  liquid  shows that the particles are packed together but is still separated. It can't flow around the area freely but the particles still sit together. The phase **solid** shows that all the particles stick together and cannot be separated in any way or form. ===

Supposing you increase the pressure of the air above the boiling liquid. What would happen to the boiling point of the water?
When you increase the pressure of the air above the boiling liquid the boiling point would increase. The air is trapped and the gas forms into liquid because of the amount of energy/heat that is formed by the trapped liquid. When the air is trapped the particles stay together with the particles making it liquid. **Imagine 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 would be fairly horrible because the pressure is low up the mountain because of how high it is and also how cold it is. The cup of tea will not heat because the it isn't at its boiling point. Therefore the cup of tea will taste fairly horrible. Does water contract or expand on changing from a liquid to a solid?** I think the water contracts on changing from a liquid to a solid. I think that because when it is liquid the particles aren't all stuck together, where as the solid is stuck together. That means when the liquid is changed to a solid the particles stuck together making less room so therefore it contracts.
