Question 9

Question
Why do objects float higher in seawater than they do in fresh water?
Answer
  • Seawater is less dense that freshwater.
  • Seawater is more dense than freshwater.
  • Seawater is more pure than freshwater.
  • All freshwater is polluted.

Question 10

Question
When aluminum foil is formed into a loose ball, it can float on water. But when the ball of foil is pounded flat with a hammer, the foil sinks. Why?
Answer
  • Aluminum is less dense than water
  • The act of pounding with a hammer, increases the mass of the ball of foil
  • The act of pounding with a hammer increases the volume of the ball of foil
  • Air caught in the ball of foil makes the ball less dense than the water
