Density (First Meeting)

Jack has a rock. The rock has a mass of 14g and a volume of 2cm³. What is the density of the rock?

• 7 mL

• 7 g/cm³

• 28 g/cm³

• 1/7 g/cm³

Which box has a higher density?  

• Box A

• Box B

• cannot be determined

• they are the same

Will an object with a density of 1.01 g/cm3 float or sink?

• float

• sink

Why do some substances float on water?

• they are warmer than water

• they are cooler than water

• they are more dense than water

• they are less dense than water

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

What is the density of water?

• 0 g/ml

• 1 g/ml

• 10 g/ml

• 100 g/ml

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

What is the formula for density?

• density = mass x volume

• density = mass / volume

• density = mass + volume

• density = mass - volume

What is the density of a solid with a mass of 100g and a volume of 50cm³?

• 1000g/cm³

• 2g/cm³

• 0.5g/cm³

• 150g/cm³
