States+of+Matter

**//__ Introduction __//**
The three most important states of matter are solids, liquids, and gases. There are many more but these are the main ones we see almost everyday. Also they can go through what is called a phase change. A phase change is when a state of matter reaches it's boiling point or freezing point. I am going to explain how the three main states of matter react to a phase change.

We see liquid everyday at school, home, or at the store. But what happens to the liquid when it goes through a phase change? Well when liquid reaches it's boiling or freezing point it changes completely. If the liquid reaches the freezing point which is at 32 degrees Fahrenheit then the liquid starts to form tiny crystals that eventually turn into a solid. Also a liquid phase can turn into a gas if the liquid reaches its boiling point at 212 degrees.

A solid phase is when a solid reaches its boiling point and starts to melt into a liquid. A great example is ice because when it is at room temperature it starts to melt, but when it is some place cold it stays the same and doesn't melt.A solid comes in many different shapes and sizes. For example a tv can come from a 12" to a 60". Solids can be melted even if it is as hard as can be. Sometimes we need to use a whole bunch of heat to melt things to a liquid.

A gas phase happens when liquid reaches its boiling point, it starts to evaporate and steam will start coming out from the liquid which is the gas. Gases has no shape and no weight, also gases release heat. Gases is what is causing the Earth to get warmer and warmer which could cause global warming. This could be a big impact to the population to humans and Earth. We are to blame for the global warming. because factories work nonstop and release gases into the air 24/7. In a few years if we don't learn we might have a big impact on global warming.
