Let’s Review the Basics
What is Mass?
Mass
is the measure of how much
matter
(little pieces) is in an object.
How We Measure It
Units are grams (g), kilograms (kg), pounds (lbs)
What is Volume?
Volume
is the amount of space an object takes up.
How Do We Measure It?
Units are milliliters (mL), cubic centimeters (cm3 or cc), and fluid ounces (fl.oz)
Let's use what we know about
mass
and
volume
for this next topic
Law of Conservation of Mass
The Law of Conservation of Mass states
:
"
mass
is neither created nor destroyed in chemical reactions"
That means...
No matter the state of matter, the amount of
mass
stays the same because it is still the same matter!
What are states of matter?
A state are the forms in which
matter
can exist.
We will be discussing 4 states of matter and their properties.
Gas
Facts
>Molecules are very weakly together
>Matter takes shape of a container
>
Volume
is same as the container
Liquid
Facts
>Molecules are loosely bound together
>Matter takes shape of a container
>Fixed
volume
Solid
Facts
>Molecules are closely bound together
>Matter holds its shape
>Fixed
volume
But wait! There's more!
Plasma
Facts
>Molecules are very weakly together (like a gas), but they are electrically conductive!
>Matter takes shape of container
>
Volume
is same as container
There are other newly discovered forms of phases, but these are the basics.
