  1. 1. Three States of matter By Brennon BHM 8th Grade Solid Liquid Gas
  2. 2. Solid  A solid’s shape and volume stay the same  Solid- the state of matter that has a definite shape and volume  Particles are very close together they have a strong attraction for each other  Solid all together (slow moving) liquids little pieces moving together gas all over moving (fast moving)  Particles vibrate
  3. 3. Solids  2 type of solids  Crystalline: Orderly, Particles in a repeating pattern of rows, particles don’t move around  Ex: iron, diamond, ice.  Amorphous: Particles have no special arrangement, Particles don’t move around.  Ex: Glass, rubber, and wax.
  4. 4. Liquids  Liquid –the state of matter that has a definite volume but takes the same shape of its container.  Particles move fast enough to overcome the attraction between some of the particles.  Particles slide past each other.  Liquids easily change shape  Liquids do not easily change volume.  Ex: if I had a glass of milk how can you change the shape of the milk? How can you change the milk’s volume?
  5. 5. Liquids  All liquids have surface tension.  Surface Tension- a force that holds together particles at the surface of a liquid.  Surface tension(ST) causes some liquids to form spherical drops (like water)  Water has a high surface tension  Rubbing alcohol has a low surface tension.  All liquids have viscosity.  Viscosity- a liquid’s resistance to flow.  The stronger the attractions between particles the higher the viscosity.
  6. 6. Gas  One small tank of helium can fill almost 700 balloons.  How is this possible? Air in the tank is under pressure when in the balloon it isn’t under pressure.  Gas – the state of matter that has no definite shape or volume.  Particles in a gas move quickly, so they can break away from their attraction for other particles  The amount of empty space between gas particles can change.
  7. 7. Gas  Particles of gas in a helium tank are close together than particles in a helium balloon.  Air is matter because it can be moved  Ex: the teacher gave us balloons and we turned a table on its back with the balloons under it and we blew it up, it lifted the table and the teacher up.
  8. 8. 2.Boyel’s Law  Boyle’s Law- at he pressure of a gas increases the volume decreases by the same amount.  a diver blows a bubble 10m below water what will happen to the bubble’s volume as it rises? It gets bigger because it has less pressure at the top.  When you put a marshmallow in an air vacuum the marshmallow gets bigger because the pressure decreases
  9. 9.  This is the video for the marshmallow man.  http://www.youtube.com/watch?v=cIVMkVSIAbw
  10. 10. A. Energy and changes of state  Change of state- The change of a substances from one physical form to another  Physical changes (substance doesn’t change)  You must add or remove energy to change the state of a substance
