Why does frozen water weigh more?

Answer 1

It doesn't weigh more. Water is more dense than ice. When water freezes, the molecules clump together. However, the molecules have space between each other, thus allowing ice to float on water.

Answer 2

it doesn't. as a liquid forms into a solid it forms more symmetrical patterns, and therefore its density increases, however there is still the same number of particles per unit mass. also this doesn't apply to water which becomes less dense when just frozen, hence ice floats.

Answer 3

Water is the only naturally occurring substance that is less dense in it's solid form.

Waters maximum density is reached at 4°C (40°F). As it cools below that temperature it becomes less dense. Water is different from most other substances because of hydrogen bonding because of hydrogen bonding. A water molecule is made from one oxygen atom and two hydrogen atoms, joined with covalent bonds. these molecules are also attracted to each other by weaker chemical bonds (hydrogen bonds) between the positively-charged hydrogen atoms and the negatively-charged oxygen atoms of neighboring water molecules. As water cools below 4°C, the hydrogen bonds adjust to hold the negatively charged oxygen atoms apart.this causes the water to become less dence and expand.

Answer 4

If you have an object suspended by a scale and lower it into water, the weight shown on the scale will decrease by the weight of the volume of water equal to the volume of the object. The water is supporting that weight; that is bouyancy. If the object weighs less than water it displaces it will not fully submerge, but will float once it has displaced the volume of water that equals its weight.

Answer 5

They weigh more in air because they displace a certain amount of water which has its own weight. The difference between these two weights is the relative weight of the object in water. A steel ship floats on water because the amount of water it displaces is greater than the weight of the steel.

Answer 6

it has a lot of mass
