Question

ice floats on water because
o of cohesion.
o ice has a lower density than water.
o water shrinks when it freezes.

Explanation:

Objects float when they have a lower density than the fluid they are in. Ice floats on water because ice has a lower density than water. Water actually expands when it freezes, not shrinks. Cohesion is the attraction between molecules of the same substance and is not the reason ice floats.

Answer:

ice has a lower density than water.
