=MY CHEMICAL PAGE! =  DEFINITIONS- DIAGRAMS-
 * Solid- A solid is a type of chemical or matter that is solid. Solids are normally hard and when don't move unless someone moves it. Some examples of solids are rocks and ice.
 * Liquid- A liquid is a type of chemical or matter that is liquid. Liquids are also wet and they can flow like water. Some examples of liquids are water and sprite.
 * Partical- A part of an object. It is usally a small portion of a matter.
 * Gas- A gas is a type of matter that is invisible. An example of a gas of a gas is oxgyen.
 * Boilling point- The boilling point is when the temperature gets really hot. When it reaches the boilling point with a liquid it would start to boil.

This diagram shows three different types substances which are solids, liquids and gases. In the solid part of the diagram you can see that all of the particals are touching each other and they are stuck together solidly so they can't break apart. They are stuck together because solids stay together and they don't natrally move. In the liquid part you can see that all of the partical are touching, but, not solidly stuck together. They are not solidly stuck together because liquids move around a lot, unlike solds, so the particals would have to move too. In the gas part of the diagram you can see that the particals are not touching at all and they are all spread out and they are a lot smaller.  QUESTIONS: Link: []


 * What is SUBLIMATION? It is when a solid turns into a gas without changing into a liquid first.
 * Supposing you increased the pressure of the air above the boiling liquid. What would happen to the BOLING POINT OF WATER? The boiling point would have to increse they can get more energy from the heat, so, they can push the blocker out of the way so it can escape.
 * Imagine that you are trying to BOILING WATER FOR A CUP OF TEA UP A MOUNTAIN. Why would the cup of tea be fairly horrible? It would be fairly horrible because up the mountain the pressure would be low causing the boiling point to rise and it would taste more like water.
 * Does water CONTRACT OF EXPAND on changing from a liquid to a solid? Water expands because solids take up more room than a liquid because in liquids the particals can move around more freely than particals in solids.
