TRANSCRIPT
Liquids
Liquids take the shape of their container and have definite volume.
Liquids have mass. Liquids take up space.
Gases
Gases spread out to fill the entire space given and do not have definite volume.
Gases have mass. Gases take up space.
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.
Particles in Plasma: Are electrically charged
Have EXTREMELY high energy levels

Add or Subtract Energy. . .
When energy is added, particles move faster!
When energy is taken away, particles move slower!
Liquid + Energy = ? When energy is added to liquids, they become gases!
What examples can you think of?
Changing States There are several names for matter changing states:
◦ State change
◦ Phase change
◦ Physical change
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?
Think About These Review Questions
1. What state of matter has definite volume and definite shape?
2. Describe the properties of liquids.
3. Describe the differences between gases and plasma.
4. What is needed for states of matter to change phase?
You will need to know this information for your assessment!
