Density

Which lab tool might you use to measure the volume of a liquid?

• electric scale

• bunsen burner

• test tube

• graduated cylinder

What two types of measurements make up DENSITY?

• Mass and Volume

• Temperature and Mass

• Grams and Centimeters

• Volume and Weight

Look at this image.  Which object has the LOWEST density in water? How? 

• The Ping Pong Ball because it floats to the top 

• The bolt because it has sunk to the bottom

• The soda cap because it is not just full of air like the Ping Pong ball

If an object has a density of 3.6 g/mL and you put it into water, will it sink or float?  

• sink

• float

Which box has a higher density?

• A

• B

• They are the same

What is the volume of 150 grams of lead if it has a density of 11.3 g/cm³?

• 13.3 g

• 13.3 cm³

• .075 g

• 1695 cm³

Find the density of a 2 cm x 2 cm x 2 cm cube with a mass of 64 g.  

(Hint: find the volume first!)

• 13 g/cm3

• 2 g/cm3

• 10 g/cm3

• 8  g/cm3

Helium balloons rise on earth because

• helium is less dense than air

• helium is more dense than air

• helium is cooler than air

• helium is warmer than air

Calculate the density of the cube.

• 2 g/cm³

• 4 g/cm³

• 6 g/cm³

• 8 g/cm³

What is the density of a material that has a volume of 20 cm³ and a mass of 380 grams?

• 0.053 cm³/g

• 19 g/cm³

• 9.5 g/cm³

• 190 g/cm³
