Presentation Transcript
Matter: :Matter: It’s what the world’s made of.
What do you know about matter? :What do you know about matter?
Solids :Solids Solids hold their own shape.
Solids have weight.
Solids take up space.
Liquids :Liquids Liquids take the shape of their container.
Liquids have weight.
Liquids take up space. !
Gases :Gases Gases spread out to fill the entire space given.
Gases have weight.
Gases take up space.
Plasma :Plasma Lightning is a plasma.
Used in fluorescent light bulbs and Neon lights.
Plasma is a lot like a gas, but the particles are electrically charged.
STATES of matter? :STATES of matter? What would it take for matter to move from one state to another?
Energy determines the state! :Energy determines the state!
Particles in Solids: :Particles in Solids: Are packed tightly together
Have very little energy
Particles in Liquids: :Particles in Liquids: Are loosely packed
Have medium energy levels
Particles in Gases: :Particles in Gases: Move freely
Have LOTS of energy
Particles in Plasma: :Particles in Plasma: Are electrically charged
Have EXTREMELY high energy levels
Mixtures may be in different phases :Mixtures may be in different phases Solid?
Liquid?
Gas?
Plasma?
Add or Subtract Energy. . . :Add or Subtract Energy. . .
What will happen? Why? :What will happen? Why?
Solid + Energy = ? :Solid + Energy = ? When energy is added to solids, they become liquids!
Examples?
Liquid + Energy = ? :Liquid + Energy = ? When energy is added to liquids, they become gases!
What examples can you think of?
Changing States :Changing States There are several names for matter changing states:
State change
Phase change
Physical change
So, did we get something new? :So, did we get something new? Ice cream and melted ice cream?
Chocolate and melted chocolate?
Ice, water, and water vapor?
Steel and molten steel?
The End! :The End!
