Question

Why does ice cube float in a glass of water?

Answer 1

Its less dense than water- water expands when it freezes...

Answer 2

ice is less dense than water

Answer 3

Because ice is about ten percent less dense than liquid water.  Get an icetray, fill it with water and let it freeze.  The resultant ice will be higher than the water was.  Water expands when frozen.

Answer 4

density

Answer 5

air gets trapped in the ice somehow

Answer 6

When water freezes and changes into a solid, its molecules arrange themselves so that they occupy more space. Which makes them lighter then the water that you put them in.

Answer 7

Ice less dense then water.

Answer 8

If u look in an ice cube then there are air bubbles and the air rises and that makes it float

Answer 9

Waters density is 2psi (Pounds per Square Inch), the density of the ice cubes in the glass is less than 2 psi, thus it floats, which is why boats stay afloat, as well as why they sink :)

Answer 10

An ice cube is denser than water because it is all put together very tightly. Denser things are lighter than less denser things.

Like hot air rises because it is less denser than cold air.

Hope I helped :)

Answer 11

water becomes ice when water at 0degree centrigate  loose its latent heat and becomes ice; but the same amount of water at 0 degree will be of less volume w. r. t. that of its ice form, means-ice is becoming of  less density compare to its form of water at 0 degree centrigrate. this is the reason why ice floats.

Answer 12

Hint : Something to do with Density.
