Properties of Matter

Learning Target - I can identify the difference between a physical and chemical property as well as note if a chemical change has occurred.

Success Criteria - I will identify if a physical or chemical property is taking place as well as chemical changes by participating in a Blooket Review game.

​S8P1. Obtain, evaluate, and communicate information about the structure and properties of matter.

Multiple Choice

What is the stuff that makes up everything?

• Matter

• Energy

• Gas

• Space

Word Cloud

How would you describe the word "property" in one to two words?

Word Cloud

List one example of a property or characteristic given in the video.

Physical Properties::

properties that can be observed directly or measured without changing the chemical identity of the substance
– Ex. Mass, volume, shape, size, color, luster, hardness, etc.

Properties of matter are like characteristics. By observing them and measuring them, we can use them to describe matter. There are two types of properties – physical and chemical.

Chemical Properties:

properties that can only be observed or measured by changing the chemical identity of a substance.
– By observing it a new substance is formed
- Ex. toxicity, flammability, combustibility, radioactivity, etc.

Physical Properties

temperature at which a solid becomes a liquid

​​Melting Point

temperature at which a liquid becomes a gas

Boiling Point

a fluid’s resistance to flow

- A physical property only of liquids

- Can change with temperature

Think “how thick it is”

- Ex. Viscosity of syrup is high and of water is low

Viscosity

how well a solvent dissolves a solute
- Results in a solution
- Ex. Lemonade

Solubility

measure of compactness or consistency of a material
- Density does not ever change
- measured by dividing mass by volume.

Density

Match

Match each picture with the type of physical change shown.

Melting

Boiling

Viscosity

Solubility

Density

• Melting

• Boiling

• Viscosity

• Solubility

• Density

Chemical Properites

​how easily a substance will set on fire

• Ex. Burning charcoal

Combustibility

how easily a substance reacts, usually with an acid or base

- Ex. explosives; mixing baking soda and vinegar

Reactivity

​how easily a substance reacts with oxygen
- Ex. Iron reacts with oxygen and moisture to create rust.

Oxidation

Match

Match the following

• Combustibility

• Reactivity

• Oxidation

Burning Charcoal

Explosives

Rust

• Burning Charcoal

• Explosives

• Rust

Physical & Chemical Changes

Matter can undergo both physical and chemical changes.

Physical Change: a change in a substance that only affects its physical properties 

Ex. Cutting, coloring, crushing, melting, boiling, etc.

Chemical Change: a change in a substance that affects its chemical properties thus a chemical reaction occurs and a new substance is formed

Ex. Burning, rusting, decomposing, etc. 

Chemical Reaction: process by which the atoms of one or more substances are rearranged to form different substances

​ States matter cannot be created or destroyed. It can only change forms.

Law of Conservation of Matter

Signs that a chemical change has occurred, resulting in a chemical reaction include: 

• Release of light

• Temperature change

• Odor change

• Sudden color change

• Gas given off

• Sudden appearance of a solid (called a precipitate)
