Physical Properties of Matter

Objective: Students will be able to recognize and name physical

properties of matter

What is Matter?

• Review:• Substances that make up the universe. • All matter has mass and volume.• 4 Phases or States of matter

Different Types of Balls

Answer the following questions related to the different types of balls:

Tennis ball, Baseball, Golf ball, Super ball 1. Are they matter?2. What phase are they in? 3. Make a list of similarities? What do all of the balls have

in common?

1. Set up a table similar to the table below.2. In the first row, using colored pencils sketch each.3. in the second row, discuss how can you distinguish each type of ball if they have all of the similarities you listed.

Tennis ball Base ball Golf ball Superball

So what is a Physical Property………

• Physical properties can be observed or measured without a change to the substance or matter. Physical properties are used to observe and describe or identify matter.

• So…….– at your table discuss and come up with a list of possible PHYSICAL PROPERTIES OF MATTER! Be prepared to share with the class.

• Physical properties include: – Amorphous - lacking definite form; having no specific shape; formless.

– Appearance – the way an object looks

– Boiling point - the temperature at which a substance changes from its liquid state to its gas state through boiling.

– Brittle - easily broken, cracked, or snapped

– Flexible - bend easily

– Color - amount of light reflected on matter that is carried on wavelengths

– Transparent – ability to see through an object

– Crystalline - having the characteristics or structure of crystals (repeating pattern; salt, sugar or diamond)

– Density - mass per unit of volume or d = m/v

– Ductile - easily stretched without breaking or lowering in material strength (example: metal being made into wire)

– Dull – lacking brilliance or luster

• Physical properties continued:– Elastic -capable of being easily stretched or expanded and resuming former shape

– Electricity Conductor - a conductor is a material which contains movable electric

charges – Freezing Point – the temperature at which a substance changes from its liquid state to

its solid state through freezing.

– Hardness/Softness – tested by using scratch tests

– Heat Conductor - capable of conducting heat

– Luster - reflects light

– Magnetism - attraction of metal

– Malleable - malleable metal is capable of being flattened into thin sheets without cracking by the processes of hammering or rolling.

– Mass - amount of matter in an object

– Melting point – point at which a substance changes from its solid state to its liquid state through melting.

• MORE Physical properties continued:– Odor - the way something smells

– Physical State (solid, liquid, gas, plasma)– Shape - the form of an object

– Solubility – the amount of solute that will dissolve in a solvent at a given temperature and pressure

– Taste – flavor

– Texture – the way an object feels (rough, smooth, soft, etc.)

– Viscosity – describes a fluid's resistance to flow (example: honey is more viscous than water)

– Volume - amount of space an object occupies

– Translucent - allows light to pass through but not detailed images
