Matter Changes States

      Hey viewers I'm back again with a new post. Sorry I have not posted anything new in some time, but I'm back and I will talk about something new today. Also, I'll be going back to my talks about matter again. Have you ever thought about why matter changes states, or how it does, or you just need a refresher course in the subject? Well, I will answer all these questions in this new post.

     
 
 
      As we should all know, matter is anything that has mass and that takes up space. You are made up of matter, the room you are in is made of matter, and yes, the device you are using to view my blog is also made of matter too. Now that we got that out of the way, lets talk about the three basic states of matter. The three basic states of matter are solid, liquid and gas. Each are unique, but all have one thing in common. Let's first talk about the differences of the three states. First, a solid has a definite shape and definite volume, and an example of a solid is ice. All solids have a melting point, which is the temperature that a solid becomes a liquid. Ice's melting point is 33 degrees F. The next state of matter is a liquid. A liquid does not have a definite shape, but it does have a definite volume. Water is an example  of liquid and is the most abundant liquid on Earth. The last one is gas, and gases do not have a definite shape or volume. An example of a gas is carbon dioxide. Even though these states of matter seem very different, they all have one thing in common. They all still keep the same chemical properties of the substance, and an example of this is water.

      Now that we know the three basic states of matter, let's talk about how a substance changes states. Substances can change states by adding or taking away heat and pressure from a substance, but adding or taking away heat or pressure will not change the substance's chemical properties. I believe that we all know what melting, freezing, and vaporization is, but you may not have heard of sublimation, condensation, deposition, and the heat of vaporization. Instead of telling you all this, I have a great video for you about this subject, and the image right below will also be of great use to you.
