The property that triggers the sense organs in the noseThe 3D characteristics of a substance

The property that allows electricity to flow through a substanceThe property that describes how compact or dense a substance is

a. Brittleness is how breakable or flexible something is?

• What is something with high brittleness (breaks easily)? _______________________

• What is something with low brittleness (very flexible)? _______________________

b. Hardness is the ability to be scratched by another substance

• What substance has high hardness (doesn’t scratch)? _______________________

• What substance has low hardness (scratches easily)? _______________________

c. Solubility – the ability of a substance to _______________ in another.

• What are some substances that do not dissolve in water? _______________________

There are two types of physical properties:

2) Qualitative properties can be described by using your . (Example: use your sense of

sight to observe colour)

They _______________ what something looks like and how it feels.

3) Quantitative properties can be ___________ . (Example: melting point, boiling point)

They are properties we measure and we use numbers to communicate them.

Some examples are:

Chemical Property: how a substance behaves when they _________________ with other substances.

Examples: reacts with water, air, oxygen or is stable, combustible

a. Reactivity – how a substance reacts with other substances to produce something new.

• Magnesium (Mg) will react with acid to produce _____________ of gas and the metal

______________. Gold (Au) will _______________ react with acid. This is one of the reasons

that gold is so valuable, and is often used for ____________________

b. Combustibility - ability to catch fire and burn in air.

• Example of a substance that is combustible ____________________________________

APPLICATIONS – which is better?

1) Helium versus Hydrogen in blimps

Helium Hydrogen- gas - gas - low density - low density- stable - flammable

2) Copper versus Aluminum pipes for plumbing

Copper Aluminum- brown - silver - metal - metal- flexible - flexible- does not rust - rusts

3) Plastic wrap versus Aluminum foil for heating

Plastic Wrap Aluminum Foil- transparent - opaque - clings - can be shaped- melts - heat resistant
