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.
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.
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.
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.
It depends how much water and how much ice you hae. if you have 1 ice cube and 6 cups of water, the water will weigh more. But, if you have 10 ice cubes and 1/4 cup of water the ice will weigh more.
If you freeze a sample of liquid water it should expand but still weigh the same amount. Water is denser than ice so by volume liquid water is heavier than water ice, thus ice floats.
if you are talking about the same glass that had water in it and THEN froze, then my friend the weight is the same. Ofcourse this is correct only if while freezing, no water spilled out of the glass (because ice takes up more space than water.
Ice water is more dense than warm water.
no. Density of ice is more than of water...we can understand from ice sinking in water drinks... Edited by Dr.J. : How is it possible for the density of ice to be more (greater) than that of liquid water if ice FLOATS on lakes and rivers? Clearly, the density of ice is LESS than that of liquid water.

yes liquid water is more dense than ice water
If you freeze a sample of liquid water it should expand but still weigh the same amount. Water is denser than ice so by volume liquid water is heavier than water ice, thus ice floats.

Ice water is more dense than warm water.
Water is "warmer" than ice. Or, to be more precise, liquid water contains more heat energy than solid water.
Ice is lighter than water. That is why it floats on water.The term "lighter" is confusing here. A pound of water will still freeze into a pound of ice. However, the the pound of ice is less dense than the pound of water, so it floats. This gives the impression that a pound of ice is lighter than a pound of water. Well really, it depends on the quantity of both ice and water. However lets say if you had 1 kilogram of ice and 1 kilogram of water. The ice would weigh more because the particles are pulled together more and they're no longer liquid (physically) and the ice would be bigger and heavier (obviously) .

Water is more dense than ice because it's molecules are closer together.
Slightly less dense. Put an ice cube in water ; it floats. It Does NOT sink.
molecules from ice is more dense than water
No, cold water weighs more (for a given volume) than hot water. This is why there is a thermocline in bodies of water. But when water freezes, the solid form weighs even less (for a given volume), this is why ice floats.
