• density
• viscosity

What is the density of a liquid that has a mass of 27g and a volume of 30ml?

• 0.9 g/ml
• 3 g/ml
• 57 g/ml
• 810 g/ml

What is the density of a substance that has a mass of 30g and a volume of 6 liters?

• 24 g/l
• 5 g/l
• 36 g/l

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

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
