States of Matter

 Hey guys, today i'll be talking about states of matter, but first you have to know what matter is. Matter is anything that has mass and takes up space. The three most commonly known states of matter are solids, liquids, and gases. Except those aren't the only states of matter, there is another called plasma. There are many different types of plasma. Some examples are: lightning, fire, and neon. The most common plasma on Earth is lightning.

Matter can also change to different states because of temperature and also because of pressure. When matter changes states it only changes physically, not chemically. An example is ice going from a solid to water, a liquid. Even though its form changed, its physical properties were the only thing that changed with it. Matter's chemical properties never change, they always stay the same.

Also, everything has their own melting and boiling points. A melting point is which a solid becomes a liquid. An example of a melting point is ice. Another part that is included in the states of matter is something called heat of fusion. Heat of fusion is the energy required to change a substance like a solid to a liquid, without changing its temperature. This energy breaks down the solid bonds, but it leaves a significant amount of energy associated with the molecular forces of the liquid state.
That's all for today people see you next week!
