Kinetic and Potential Energy

      Hi today's blog is Kinetic and Potential energy. The picture on the right is just to get your attention. So I hope you know nothing about Potential and Kinetic energy.



    Lets start with what it is energy is something or someone giving off power. Potential energy is something that is going to have energy like a this truck before it got smashed. Kinetic energy is when something is moving like the truck getting smashed.










       Kinetic energy can be transferred when two objects collide. Like when a car hits a car. Energy and not be created or destroyed but it can be transferred or stored. The amount of energy an object has is due to its mass and speed. To get the most potential energy an object has to go high in the air when an objects goes high in the air it has the most energy. So if two books on a bookcase are side by side  the one with the most wieght would have the most potential energy. The one with less wieght would have less energy.


      Hope you liked the blog. Comment what you think of the blog. So thats all today BYE.

States of Matter

       HI today i'm going to blog about the States of Matter. I'm going to be talking about the three states of matter and how it changes states and a lot of other info on matter. Has you can see in this pic it shows you how it gets to the other states by adding heat and energy.









       First i'm going to tell you what matter is in the first place its anything and everything that takes up space.  To change a state of something you have to decrease or increase the temperature. The boiling point is when a liquid gets heated up and boils . The melting point is when a solid turns to a liquid. Like when an ice cube melts and turns into water. When something changes state it does not change its atoms and things like that. Now you know what the melting point is and boiling point and matter lets talk about states of matter. Solid is a fixed shape and the molecules are tightly packed together. Liquid is not a fixed shape and it takes the shape of the container its in. The molecules in a liquid are tight but able to move around. Each liquid has its own special boiling point and melting point like water has a 0C melting point and a 100C boiling point. Gases molecules are spread out and bouncing around it also has no fixed shape.



     Sublimation is when a solid go's into a gas skipping the liquid state. An example of sublimation is dry ice .Condensation is when a gas go's into a liquid. On this pictures it shows that air hits the glass and the glass is cold so it turns the air into water. Heat of vaporization is the amount of heat required to convert a unit mass of a liquid at its boiling point into vapor without an increase in temperature. Heat of fusion is when you turn a solid into a liquid without increasing the temperature.
