Floating and Sinking

Buoyancy is the ability to

• Sink

• Float

Density is the amount of ________ per unit of volume

• gravity

• mass

• motion

An object will sink in water if it...

• is more dense than water

• is less dense than water

• has the same density as water

An object will float on water if it...

• is the same color as water

• has the same density as water

• is more dense than water

• is less dense than water

Density equals

• volume x mass

• mass divided by volume

• force x area

In iceberg floats in the ocean. The ice must be ________ than the liquid water.

• less dense

• more dense

A helium balloon floats away because helium is _______ dense than air

• more

• less

 $2.0g\div2.0cm^2$  find the density

• 1.0g/cm3

• 2.0g/cm3

What is the formula for density?

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

Why does ice float?

• Liquid water is less dense than solid water.
• Solid water is less dense than liquid water.
• Gaseous water is less dense than solid water.
• Liquid water is less dense than gaseous water.
