Solids- Solids are particels that are very tightly packed like ice is a solid. The closer the particels are the harder it gets, just like diamonds, their paricels are very tightly packed that it is hard and you basically can hold solids. Diamonds and ice can not become smaller, unless for diamonds, you brake it and for ice you try to melt it. So solids are basically anything hard such as desk, crystals, tv...

Liquids- Water is a liquid and even your blood is a liquid, the particels in water and blood are closely packed together, but it can easily slide over each other so that is why liquids isnt hard. Liquids fill out shapes of things, for instance, when you put some water in a container or a glass, the water would stay in a shape of the container or the glass or anything that you put liquid in.

Gases- The particels of the gas are spread out, so that is why that gas can move around easily. Gases can fill out a container or any part of things, and of course balloons. When you blow up a balloon, gases goes inside and spreads out in the balloon, and when you blow up the balloons, the gas spread out i and it expands to fill up the balloon. Gases are also around you, it is basically air. Sometimes the breeze of air go thorugh your face, and it that's an example of how gases are around you.




 * Solids, Liquids, Gases

What is sublimation?** Sublimation is a solid going to gas without becoming into a liquid. e.g dry ice

What would happen to the boiling point of the water?** If you increased more air pressure, it would be harder for the gas to escape. So you need to increase the heat so gas can escape.
 * Supposing you increased the pressure of air above the boiling liquid.

Why would the cup of tea be fairly horrible?** When you are boiling water up a mountain, the water would be boiled but when you pour the water in the cup of tea, the tea becomes slightly colder
 * Imagine that you are trying to boil water for a cup of tea up a mountain.


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