Matter

Matter- Solids Liquids Gasses Gels

Properties of matter

The properties of matter observable

How it looks: Shiny, dull, color, etc. How it feels: Hard, soft , rough,

smooth How it smells: Sweet, sour, odorless How it sounds: Loud, soft, no sound What it does: Magnetize, stretch,

break , tear, bounce

States of matter

Solid- Liquid- Gas- volume

It will take up the space provided

Measuring matter

Volume- Graduated cylinder

Mass- Triple beam balance

Density- Mass/volume = density

Vocabulary Solution- a liquid mixed with another substance

so that they become one Characteristic property- a property that only

that substance has Melting Point- point at which a substance goes

from a solid to a liquid Boiling point- point at which a liquid becomes a

gas Physical change- change in the shape, texture,

or feel of a substance Properties of matter- observable attributes Matter- something that has mass and volume Compound- two or more substance chemically

combined Chemical Change- change in the chemical

makeup of matter

Physical changes in matter Cut Tear Fold Tint Bend Melt Dissolve

Bell Ringer

List 3 chemical changes in matter.

Chemical changes in matter Changes the state of matter to

something else Burn, rust, chemical changes, etc.

Characteristic Properties

Characteristic Properties-

Ex- Boiling point, melting point, freezing

Two Types of Matter

Pure Mixture

Pure substance-

Ex- Sugar, salt, iron, copper

Mixture-

Ex- Salt water, fruit juice

Elements (Pure)

Elements-

They can not be broken down into simpler substances by chemical or physical means

Compounds (Pure)

Compounds-

Ex- H2O (water), CO2 (carbon dioxide), C12H22O11 (sugar)

Can be broken down by chemical reactions

This is how we get all the matter we have around us. The 100 or so elements on earth combine in different ways to make millions of different matter with different properties.

Solution

Most evenly mixed type of mixture Ex- Sugar water

Review1. List the three states of matter.

2. What is meant by a characteristic property of matter?

3. List 5 ways to physically change matter and 3 ways to chemically change matter.

4. Give an example ofa) Mixtureb) Elementc) compound

Density

Density = Mass per unit volume D= Grams/ cm3 (solid) D=Grams/ml (liquid)

Ex- D = 100 g/ 8 cm3 = 12.5 g/cm3

Density

I have a block that weighs 213 grams. It is 3 cm by 2 cm by 4 cm.

What is its density? Will it float or sink in water?
