Why does ice weigh more than water?

Answer 1

Ice weighs more than water because of the difference in molecular structure. When water freezes into ice, the molecules arrange themselves in a more spaced-out, hexagonal lattice structure, which increases the volume of the substance. Despite the increase in volume, the mass remains the same, resulting in a higher density and therefore more weight per unit volume compared to liquid water.

Answer 2

Actually it is not. The same volumn of ice is lighter than water because the water has greater density with no air trapped inside. Ice, on the other hand is less dense. You will notice that if you drop an ice cube in water it will float. If it were heavier than the water it would sink.

Answer 3

It doesn't. Ice is less dense than liquid water, which is why it floats in water. If you determine the mass of equal volumes of ice and liquid water, the water would have a greater mass than the ice.

Answer 4

It isn't.

Otherwise ice would sink to the bottom of a drink instead of floating on top.

Generally change in volume of a substance is proportional to the change in its temperature. But water shows different behavior between 0 degree and 4 degrees centigrade. Water freezes at 0 degree centigrade and therefore it has more volume and thus lower density as compared to water in liquid state. Therefore, it floats in water.

Answer 5

Ice is less dense than liquid water, which means that the same volume of ice will have more mass compared to an equal volume of liquid water. This is because when water freezes into ice, its molecules organize into a more ordered structure, increasing its mass without changing its volume.

Answer 6

This is because ice epand when it freezes, so the ration would change. If water is 100lbs/1foot, when you freeze it it would be something like 100lbs/1.68feet.
