Physical Property

Characteristic of a pure substance that can be observed WITHOUT changing it into another substance.

Physical Properties of Matter

• It does NOT CHANGE into something else• Examples

color shapetaste

state/phasedensity

D = m V

Physical Change

• a change in shape, size, color, or state• a change without a change in chemical

composition

• a change that is reversible• The Mixtures Lab

• Examplestearing paper

cutting your hair change in state

Chemical Property

A characteristic of a pure substance that describes its ability to change into a DIFFERENT substance.

Chemical Properties of Matter

• changes into a new substance• Examples

flammabilityreactivity with vinegarreactivity with oxygen

Iron + Oxygen Iron oxide (rust)2Fe + 3O2 Fe2O3

Chemical Change

• a change in which a substance becomes another substance having different properties

• a change that is not reversible using ordinary physical means

• Changes that usually cause heat, sound, light, odor, fizzing/foaming, color changes

• Examplescombining sulfuric acid and sugar

burning a piece of woodsoured milk

Chemical or Physical Property?

1. Paper is white

2. Boiling point of H2O is 100oC

3. Zinc reacts with hydrochloric acid and creates hydrogen gas

4. Nitrogen does not burn

5. Sulfur smells like rotten eggs

I.S. Learning Goal:•I can describe predict properties of elements and compounds using trends of the periodic table (e.g., metals, non-metals, bonding – ionic/covalent).

Comparing Physical and Chemical Properties

Substance/Matter Physical Property Chemical Property

Helium Less dense than air Nonflammable

Wood Grainy texture Flammable

Baking soda White powder Reacts with vinegar to produce bubbles

Powdered sugar White powder Does not react with vinegar

Rubbing alcohol Clear liquid Flammable

Red food coloring Red color Reacts with bleach and loses color

Iron Malleable Reacts with oxygen

Chemical or Physical Change?

1. Bending a Paper Clip

2. Baking a cake

3. The sublimation of carbon dioxide

4. Crushing an aluminum can

5. Vinegar and baking soda combining to create salt and water

3. States of Matter Note Page for 10 Points due 11/4/2013

Schedule:• Notes: 4 States of

Matter• Grade Checks

Objective: I can differentiate between the four states of matter

4 Physical States of Matter

• Solid • Liquid

• Gas• Plasma

Solid

• Particles are tightly compact

• Particles vibrate without the ability to move freely

• Definite shape and volume

• Solid Animation

Liquid

• Particles are tightly compact, but able to move around close to each other

• No definite shape, but definite volume

• Liquid Animation

Gas

• Particles can easily spread out or move close together

• Particle move freely and with a lot of energy

• No definite shape or volume

• Gas Simulation

Plasma

• Exist at extremely high temperatures (several million degrees Celsius)

• Particles are broken apart• Particles move freely and

with extremely high energy

• This form is not too common on Earth, however it is the most common form of matter in the universe

• No definite shape or volume (?)

• Examples: Florescent and neon lights, lightning, aurora borealis

Why do you think this is the most common form/state of matter in the universe?
