#### Transcript of Properties of Matter: Volume, Mass, and Density

**Understanding the Properties of Matter:**

VOLUME

What is Matter?

**DENSITY**

DENSITY, VOLUME, AND MASS

What you should know:

Density is how much mass is in the space the material occupies. It's the number of atoms within a given amount of space.

**MASS**

Matter is anything that takes up space. Matter is everywhere. Matter is made of atoms.

If it has mass & takes up space, it's matter!!

Volume is the amount of space occupied by something. Volume can be measured by water displacement.

Mass is the amount of matter in an object. Be careful though!! Mass and weight are NOT the same!! Weight is the force that a particular mass feels when gravity is pulling on it. (Gravity affects weight and not mass.)

Mass remains the same no matter where you are-even on the moon!!!

Calculate the density of the following:

A coin

mass=12g

volume= 4mL

A cell phone

mass=180g

volume=90mL

EQ: What is the relationship between the volume and mass of matter?

Formula: D=M/V

Density= mass divided by volume

Why does ice float in liquid water?

A difference in density!

Water Displacement Method

Measure the difference in water level before and after you add an object

final volume-initial volume= volume of object

What are the units of density based on your calculation?
