Properties of Matter
These are used to describe and identify matter.
Properties
A phase of matter in which the matter holds its shape
solid
physical
What type of change happens when two substances are mixed and a new substance is formed.
Chemical change
The study of what matter is made of and how it changes is called
Chemistry
The ability of a magnet to attract metal is
magnetism
Another word for vapor is
gas
Why or why not?
No. The matter is conserved because no new matter is added or taken away.
During a chemical change, what happens to the total weight of the matter?
It stays the same.
atoms
The ability of a substance to dissolve is called
solubility
An action in which matter changes from one phase to another
phase change
Name the three states or phases of matter.
solid, liquid, gas
Give an example of a chemical change.
sample answers: burning wood, making slime, baking bread/cookies/cakes, lighting a candle, breaking a glow stick, mixing baking soda and vinegar
Matter made of a single type of atom is an
element
Name three properties of matter.
Solubility, buoyancy, hardness, reflectivity, magnetism, conductivity, color, strength, texture
Proof
evidence
Describe physical change.
Give evidence that a chemical change has happened.
light is emitted, temperature change, color change. precipitate forms, gas forms, change in properties, odor change
Atoms of different atoms that form bonds with each other are called
molecules
How can we use evidence to describe matter.
We can observe matter to tell its physical properties .
A system in which matter can escape or be added
open system
How would you prove that the mass of matter is conserved during a physical change?
You can measure the mass of the matter before and after the change happens.
Name the evidence that a chemical change happened when you light a match.
light is emitted, temperature change
A molecule of water is made of which atoms
two hydrogen atoms and 1 oxygen atom
