Mini-Quiz: How Objects Float in Fluids

by Ron Kurtus (revised 23 June 2015)

Take this Mini-Quiz to check your understanding of the lesson material.



1. Since carbon dioxide is more dense than air, what happens to a CO2 balloon?

It floats upward

It falls to the ground

It explodes

2. If a material had a density of 0.8 gm/cm3, what percentage would be above the waterline?

20%

80%

100%

3. Since lead is more dense than steel, could a lead boat float in water?

No, only steel boats will float

Lead dissolves in water, so you could never find out

Yes, provided it is hollow and has a lower density than water

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.
