Question

The fact that water is attracted to itself, a property called , leads to another important property, the liquid form of water is dense than the solid form. As water solidifies into ice, the molecules must move apart in order to fit into a crystal lattice structure, causing water to expand as it freezes. Because of this, and water sinks, which keeps the oceans liquid and prevents them from freezing solid from the bottom up.

Answer 1

As the first blank is already filled, this first property is called the Cohesive property of water, which is what makes it possible to clump together into drops, due to their intermolecular forces.

The second blank is talking about density, and as we can see in our daily lives, ice is less dense than water, therefore in this blank liquid water will be MORE dense than ice, this is due to the hydrogen bonds and the orientation in which they are causing the molecules to push farther apart.

As we have discussed in the second blank, this 3rd blank is ICE FLOATS
