Question

Which of the following describes why ice floats?
A)The density of ice is higher than that of liquid water.
B) The density of ice is lower than that of liquid water.
C) The density of ice is the same as liquid water.
D) None of the above

Answer 1

Ice is actually LESS DENSE than water.

LESS DENSE means that its molecules aren't tightly packed together.

That's why there's a lot of air, inside of ice.

And THAT is why ice floats on top of water.

Water is MORE DENSE than ice.
