Im not understanding what you are trying to ask in the question.
Is there answer choices?
Is there a paragraph to go with it?
Water has special characteristics because liquid water is denser than ice and ice floats on top of liquid water.
Answer: Option A & D
<u>Explanation:</u>
A water molecule is formed by the covalent bonding between two atoms of Hydrogen atom with one atom of Oxygen. In water, the Hydrogen bonds are the one that keeps the water molecule intact.
When the water molecule freezes the bonding becomes weak as they are separated and set apart which makes the liquid water denser than ice. Normally a substance floats if it is less dense. Ice floats because it is less dense than water.
The military will change lots like right now there replacing the Humvee with the mrap and the m1 abrams is being replace to there also making liquid armor and robots to oh ye and that armor stuff that has a exo skeleton to help carry the armor and supplies<span />
