• Mass and Acceleration

• Mass and Volume

• Length and Width

Which object has the lowest density in this picture?

• A

• C

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

Answer explanation

Less dense substances will always float on higher density substances.

What is the formula for density?

• density = mass x volume
• density = mass / volume
• density = mass + volume
• density = mass - volume

Which liquid is the least dense?

• oil
• water
• syrup 
• plastic bottle
