For example; A piece of ice is a solid. The process of melting because the temperature around the ice is not a freezing point then tuns the ice into a liquid. This is a physical change.

For example;  You put a water bottle filled with water in the freezer. You come back and check it two hours later. The water is frozen.  The water went from a solid to a liquid because the temperature was at a freezing point and the liquid reacted. this is a physical change.

The liquid can turn to a gas if the pressure or temperature is changed. For example; It rained yesterday. You are going outside on an early morning for a run. You see fog on the field next to you. Fog is a form f evaporation, fog comes from cool air being above a warm body of water. The water molecules evaporated and quickly humidified into the air causing fog. This is a physical change.

For example; It is a hot summer day and you sit a cold can of soda on a picnic table. The soda can is wet a few minutes later.  This is condensation. Vapor molecules collided with the colder surface (the can) and turned into liquid water. This is a physical change.

For example; you can freeze ice and then dry it. You can see the gas coming from the ice cube.]]> 2018-02-02 14:10:30 UTC https://padlet.com/lwilliams029/q5y4m0df6rpg/wish/227486725 lwilliams029 https://padlet.com/lwilliams029/q5y4m0df6rpg/wish/227528558 A solid is something that is made up of particles that are held tightly and firmly together. This gives the solid a definite shape and volume. ]]> 2018-02-02 15:27:33 UTC https://padlet.com/lwilliams029/q5y4m0df6rpg/wish/227528558 lwilliams029 https://padlet.com/lwilliams029/q5y4m0df6rpg/wish/227530819 a liquid flows freely, and has the consistency of water and or oil. The particles in a liquid begin to liquefy from a solid when the temperatures of the both freezing and hot are the same, this is called the melting point. Liquid particles take up the shape of their solid container because they have more kinetic energy. Liquids do not have a definite volume because they cannot completely overcome the forces that are attracted that hold them together.

Gases have a lot of kinetic energy to defeat the attractions between them so the particles can escape the liquids surface, this is vaporization. Gases do not have a volume or shape. ]]> 2018-02-02 15:51:38 UTC https://padlet.com/lwilliams029/q5y4m0df6rpg/wish/227541318 lwilliams029 https://padlet.com/lwilliams029/q5y4m0df6rpg/wish/227545067 Positively and negatively charged particles at extremely high temperatures is called plasma. Negatively charged electrons roam freely. through positively charged ions. Stars neon lights, and lightening are where plasma can be found. Plasma is the most common state of matter, because the particles in plasma are moving so fast the electrons are actually stripped from the atom.]]> 2018-02-02 15:58:27 UTC https://padlet.com/lwilliams029/q5y4m0df6rpg/wish/227545067
