Chapter 3: Matter and Its Changes
Section 1: Physical Properties and Changes
A. _______________—any characteristic of matter that can be observed or measured without
changing the identity of the matter: a _________ change makes physical properties change, but
their identity remains the same.
1. Any characteristic that can be observed or measured is a physical property.
i. ____________can be measured.
ii. ____________(amount of material in an object) can be measured.
iii. ____________ is a measure of how much space an object takes up;
iv. _____________ is the amount of mass a material has for a given volume.
Circle the picture that is more Dense. Circle the picture that is more Dense?
It is not always easy to know by looking at objects. A Pepsi can and diet Pepsi can look alike. If we
dropped them both in water (displacement) then the water should rise the same amount for both cans:
meaning that they have the same ___________. But, they could have different masses as we learned in the
lab when we used the triple beam balances. They also might have different ____________. You would
find an object’s density by using this formula. D= m/v.
1. Density changes as pressure or ______________ changes.
This ball does not float at 15
degrees Celsius, but does float at 40
degrees Celsius. Why would that
be?

v. Physical appearances can be observed (5 senses)

2. B. Solid,____________, gas and plasma are four states of matter. An objects state of matter depends
on its temperature and pressure.
1. Matter is made up of ____________ particles. Matter in the plasma phase have the most
energy, gas has less than plasma, liquid has less energy than gas, and solids have less
energy than liquids.
2.
______________ point—temperature at which a solid becomes a liquid (ice melting)
3. ______________ point—temperature at which a liquid becomes a gas (water boiling)
C. ____________properties can include luster, malleability, ductility, and magnetism.
D. _____________ properties can be used to identify, classify, and separate substances.

3. Section 2: Chemical Properties and Changes
A. _____________Property—characteristic that gives a substance the ability to undergo a change that
results in a new substance
1. Flammability
2. Reacts with oxygen, light, water, or other substances

B. Chemical ____________—change in the identity of a substance due to its chemical properties.
1. Signs of a chemical change include the production of bubbles, heat, light, smoke, sounds
or color changes.
2. Chemical changes are not _____________ using physical means.

C. Law of conservation ________________—mass is never lost or gained in a chemical reaction.
1. When material is burned, residue is less massive than original material
2. Ash, smoke, and gases escaped into the air—they are still considered matter.
3. Their mass was not lost, only ______________.
