Properties of Matter: Volume, Mass, and Density
Transcript of Properties of Matter: Volume, Mass, and Density
What is Matter?
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.
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 cell phone
EQ: What is the relationship between the volume and mass of matter?
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?
