States of Matter
Earth Science Intro Unit
I will be able to define and describe matter and the four states of matter.
What are the states of Matter?
All matter is made of atoms.
Atoms are in constant motion.
Particle movement determines the state of matter.
States of Matter.
Very close together.
Vibrate in place.
Further apart just enough to allow movement
Move, have more kinetic energy.
Kinetic energy is the energy of motion.
Particles are far apart
Moving very fast.
Most kinetic energy.
Move faster when heat is applied.
Move slower when heat is taken away.
What are the states of Matter
Plasma: 1000 C- 1Bill C
A good conductor of electricity
Is affected by magnetic fields
Common State of Matter
STATES OF MATTER
Tightly packed, in a regular pattern
Vibrate, but do not move from place to place
Close together with no regular arrangement.
Vibrate, move about, and slide past each other
Well separated with no regular arrangement.
Vibrate and move freely at high speeds
Has no definite volume or shape and is composed of electrical charged particles
I will be able to explain what a change in state is and describe how matter changes state.
What is a change in State?
Changes in States
A change of a substance from one physical state to another.
Water vapor to liquid water.
Liquid water to ice.
Energy Gained or Lost
To change state, energy must be added or removed.
Gaining or losing energy changes the temperature of a substance.
What happens to matter when a change of state occurs?
Energy / Motion of Particles.
Vibrate in place, particles close together
Particles further apart.
Particles very far apart.
Solid becomes liquid.
Energy is added
Particles speed up.
Temperature at which a substance changes from a solid to a liquid.
Process by which liquids or solids change to a gas.
Change in state from a solid directly into a gas. (skips liquid phase)
Atoms gain energy
Escape into the air as a gas.
Example: Dry Ice
Add heat to a liquid
Atoms gain energy.
Particles can escape from the surface of a liquid if enough heat is added.
A rapid change from a liquid to a gas (vapor)
The temperature at which this occurs in a liquid.
The change in state from a gas to a liquid.
Cooling a gas
Particles lose energy.
Change in state from a gas directly to a solid.
Atoms lose energy
No liquid forms in the process.
Water vapor turns into ice crystals.
Liquid becomes solid.
Loss of energy.
Particles slow down
Temperature at which a substance changes into a solid.
Water = 0C or 32F
Mass is Conserved
The amount of matter stays the same during a phase change.
The mass does not change when its state changes.
Each state contains the same amount of matter.
Equal Amounts of Positive and Negative Electrons
I will be able to explain what a change in s
