Because solid water is less dense than liquid water, ___ floats.

• solid water

• liquid water

Why does ice float?

• As water freezes, it expands and its density decreases.
• As water freezes, it takes up more hydrogen from the atmosphere, causing it to have a greater buoyancy.
• As water freezes, air becomes trapped between the hydrogen bonds of water molecules.
• As water freezes, it takes up more oxygen from the atmosphere, causing it to have a greater buoyancy.

Which of the following best describes a supersaturated solution?

• a solution that contains the maximum amount of solute that is capable of being dissolved

• a solution that contains less than the maximum amount of solute that is capable of being dissolved.

• a solution that contains more than the maximum amount of solute that is capable of being dissolved.

• none of the above

What do you call a solution that contains less than the maximum amount of solute that is capable of being dissolved?

• unsaturated solution

• saturated solution

• supersaturated solution

• insoluble solution

• 5 g

• 10 g

• 20 g

• 39 g
