I can describe the properties of the different states or phases of matter.

Last Week’s ObjectivesI can describe the ZOMBIES symbiotic relationship using scientific terms. (Fri. 10/30)

I can explain the differences and similarities among the various types of mixtures. (Thurs. 10/29)

I can differentiate between compounds and the types of mixtures -homogeneous and heterogeneous. (Wed. 10/28)

I can classify matter as element, compound, or mixture. (Tues.10/27)

I can describe the properties of matter and explain how the properties can be changed. (Mon. 10/26)

ESSENTIAL QUESTIONS• How can you classify matter?• What is a substance? • How do mixtures differ from substances? • How do atoms of different elements differ?� Identify specific samples of matter as elements, compounds, or mixtures based on their known properties. DOK 2� Categorize “models” of matter as elements, compounds, or mixtures. DOK 3

PHASE CHANGES

KINETIC THEORY OF MATTER

Matter is made up of particles which are in continual random motion.

WHAT ARE THE 4 STATES OF MATTER?

SolidPlasma

Gas

Liquid

SOLIDS:•Solids have a definite shape and volume

•usually organized, crystalline solid

•Softer solids will have no pattern, amorphous solid.

•packed tightly together•Vibrate in place

PARTICLES IN LIQUIDS:•Liquids have a definite volume

•Liquids take the shape of their container.

•Liquids are a fluid •Far enough apart to slide over one another

•Energy level is greater than in solids

PARTICLES IN GASES:•No definite volume or shape.

•Gasses spread out to fill the entire space given.

•Can be squeezed together•Particles are very far apart and move freely

•Collide frequently•Have LOTS of energy

PARTICLES IN PLASMA:•Plasma is a lot like a gas, but the particles are electrically charged.

•Have indefinite shape and volume.

•EXTREMELY energetic•Lightning is a plasma.•Used in fluorescent light bulbs and Neon lights.

STATES OF MATTER

SOLID LIQUID GAS PLASMA

Tightly packed, in a regular

patternVibrate, 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

WHAT IS A PHASE CHANGE?

• A change from one state of matter to another

• Phase changes are physical changes because they do not affect the chemical make up of a substance.

WHAT HAPPENS DURING A PHASE CHANGE?

•During a phase change heat energy is either absorbed or released

•Heat energy is released as molecules slow down and move closer together- exothermic

•Heat energy is absorbed as molecules speed up and expand-endothermic

MELTING

•Phase change from a solid to a liquid

•Molecules speed up, move farther apart, and absorb heat energy

FREEZING

•Phase Change from a liquid to a solid

•Molecule slow down, move closer together and release heat energy.

VAPORIZATION (BOILING)

•Phase change from a liquid to gas. It occurs at the boiling point of matter.

•Molecules speed up, move farther apart, and absorb heat energy.

EVAPORATION•Phase change from a liquid to a gas on the surface of a liquid (type of vaporization).

•Molecules speed up, move farther apart, and absorb heat energy.

CONDENSATION

•Phase change from a gas to a liquid.

•Molecule slow down, move closer together and release heat energy.

SUBLIMATION

•Phase change from a solid to a gas.

•Molecules speed up, move farther apart, and absorb heat energy.

DEPOSITION

•Phase change from a gas to a solid.

•Molecules slow down, move closer together and release heat energy.

PHASE CHANGE OF WATER1. Why is there no

change in temperature during a phase change?

2. Define melting and boiling point.

3. What is the melting and boiling point of water?

4. At what temperature does water freeze and become a solid?

Explain how the types of phase changes differ. Give an example where this will be useful in everyday life.
