why is ice less dense than water at room temperature?

Question

i need this and fast please!!!!!!!!!!!1

Answer 1

Density is equal to mass divided by volume. d = m/V

Because of hydrogen bonds, the structure of ice is very spread out. Let's say you freeze 10kg grams of water. Now you have 10kg of ice. Since the hydrogen bonds make the ice structure spread out, you have a bigger volume. According to the formula d = m/V, if the mass stays the same, and the volume increases, then the density MUST decrease.

Answer 2

Ice does no longer exist at room temperature and rigidity. At 0 levels Celsius, the water molecules in ice are prepared in a crystalline structure which truly has the molecules farther aside than in liquid water. The molecules are farther aside, and for this reason the sturdy takes up better quantity, and is way less dense.

Answer 3

Hydrogen bonding between the molecules is more rigid in a solid (ice) and as stated above - this keeps the water molecules farther apart in a lattice-type structure that is less dense than liquid water.

Answer 4

There are, I believe, 3 elements that are less dense in the solid form and ice is one of them. It is due to the crystal structure.

Answer 5

Ice is less dense than water in any temp and is melted into water at room temp.

Answer 6

Because when water crystalizes into a solid - forming ice - it's molecules are farther apart than water in its liquid form; therefore ice has a lower density than its warmer counter part, so it floats!

Answer 7

the structure of crystalline ice make the bond stretch more far and the water molecule as ice structure will be lighter and float

Answer 8

what? ice at room temperature is water!

Answer 9

I wonder why ice floats
