Intro to Density
1. What is mass effected by?
2. Will changing the volume change the density?
How tightly packed the particles are in a substance.
vs.
A block of iron has very tightly packed particles compared to a block of aluminum.
NO. Density is a RATIO between mass and volume….the particles remain packed the same way no matter what the size of the sample.
3. What does DENSITY measure?
4. What are three ways to find volume?
Density measures the amount of particles (mass) in a certain space (volume).
vs.
Which is wood? Which is iron? Why?
1) Use a G.C.2) bxh3) displacement
6. How do you know where to put each number variable in the formula?
‘
7. Will changing the volume change the mass?
Yes. You will have more particles so more mass. BUT the density is the same.
5. What is the Density Formula?
D = m/v
• IDENTIFY # by UNIT LABEL• Mass #’s = GRAMS• Volume #’s = mL, cm3, cc or
any Liter or Cubic unit• Density #’s = Combination unit
labels: g/mL or g/cm3 or g/cc
vs
The length is 3 cm the width is 4 cm and the height is 5 cm.
The length is 4 dm, the width is 6 dm and height is 9 dm. The volume is?
The length is 10 m, the width is 4 meters the height is 7 meters. The volume is?
