Matter is anything that has volume and mass.

The volume of the liquid is measured by graduated cylinders

When you measure the volume of liquid remember to look at the meniscus

Mass: amount of matter in an object Volume: amount of spacean object occupies

What is matter? Essential Question: What are the

differences between the four states of matter?

What are the four states of matter?

They have definite shape and volume Particles are pact Particles vibrate in place

Describe solids

Liquids take the shape of the container

Liquids have definite volumeParticles slide past each other Particles are not packed; they are spaced

out.

Describe liquids

Gas changes their shape; indefinite shape

Gas changes their volume; indefinite volume

Particles are extremely far away from each other; particles move freely

Describe gas

Plasma conducts electricitySame properties as gas

Describe plasma

Topic: Describing MatterEssential Question: Give different examples of

chemical and physical changes

Physical PropertiesCan be observed or

measured without changing the identity of the matter.

Chemical propertiesThe ability of the

substance to change into a new substance with different properties.

Thermal conductivity

Changes of states of matter

What are some Physical Properties?

Ductility:The ability to be drawn into Wires.

Malleability:The ability to be poundedinto thin sheets.

Density:Mass/volume g/cm3

Solubility: sugar dissolvesin water. Sugar is the solute, water is the solvent

Chemical properties The ability of the

substance to change into a new substance with different properties.

Ex: wood burning and changing into ash and smoke

Ability to burn: Flamability

Physical changes Freezing water for ice

cubes Sanding a piece of

wood

Bending a paper clip Mixing oil and vinegar Crushing an aluminum

can Cutting your hair

Let’s Review

Match each physical property in column B to the correct phrase in column A

Column A Column B

____ sand does not dissolve in water

a. State

____ gold can be made into gold foil; thin sheets

b. Thermal conductivity

____ ice is the solid form of water.

c. Solubility

____ copper can be drawn out into wire.

d. Density

____ a foam cup protects your hand from being burned by the hot chocolate the cup contains.

e. Ductility

____ ice cubes float in a glass of water.

f. malleability

Put a check mark in the appropriate column to indicate a physical or a chemical property.

Sharpening a pencil

Alka-seltzer reacting with water

Paper burning

Tearing paper

Which of the following represents ONLY physical propertiesa. flammable- dense, malleableb. malleable, reactive, densec. powdery, dense, redd. clear, grainy , flammable

It is a pure substance that cannot be separated into simpler substance by physical or chemical means.

Each element has it own atomic number (# OF PROTONS)

Element

When a new substance is formed Examples : Sour milk, effervescent tablets,

and the Statue of Liberty

Clues to chemical changes: Color changeFizzing or foamingHeatProduction of sound, light, or odor

Chemical change:

Two or more elements combined chemically together. Compounds can only be separated by chemical means.

Compound

Two or more elements combined physically together. They can be separated by physical means only.

Mixture:

Similarities between Compound and mixturesMade out of two or more elements

Compounds cannot be separated by physical change while mixtures can.

Compounds do not retain the identity of their combined elements, while mixtures do.

Compounds must have certain ratio ( H2O)

While mixtures can be formed by any ratio

( Pizza, you can add and take out things to it)

Differences between compounds and mixtures:

Two types of mixture

Can tell what the mixture is made out of

Cannot tell what the mixture is made out of

Heterogeneous mixture

homogeneous mixture
