Density Pre-Test

The amount of matter in an object

• volume
• density
• mass
• atom

The amount of mass per unit of volume of an object or substance

• volume
• density
• mass
• atom

A method used to find the volume of an irregular object

• mass

One side of a cube is 7cm long.  What is the cube's volume?

• 7 cubic cm
• 49 cubic cm
• 21 cubic cm
• 343 cubic cm

Calculate the density:
Mass- 16,000g
Volume- 800cm3

• 2g/cm3
• 20g/cm3
• 200g/cm3

What does density have to do with atoms?

• It describes how they float
• It tells how many atoms an object has
• It describes how closely the atoms of an object are packed together

A tiny piece of sand is very light, but it sinks in water.  This is because...

• sand is a solid
• sand is less dense than water
• there is more water than sand
• sand is more dense than water
