Review: Density, Measurements, Graphing

Density can be defined as,

• A measure of how tightly packed the molecules are in a substance
• The amount of space an object takes up
• The amount of matter in a substance
• The distance between one point to another

Volume can be defined as,

• A measure of how tightly packed the molecules are in a substance
• The amount of space an object takes up
• The amount of matter in a substance
• The distance between one point to another

What is the density of water?

• 2.0g/mL
• 1.5g/mL
• 1.0g/mL
• 0.1g/mL

Which phase of matter has the highest density?

• Solid
• Liquid
• Gas
• Plasma

When placed in water, an object with a density that is less than water will

• Sink
• Float
• Stay in the middle
• Break

If four liquids of different densities are placed in a beaker, how will the liquids stack up?

• The most dense will be on the bottom, the least dense will be on the top
• They will all mix together
• The least dense will be o the bottom, the most dense will be on the top

What instrument is used to determine the volume of a cube?

• Ruler
