Why does my ice melt in my soda?

Answer 1

Pure water ice cubes always float. They float because the molecules of water rearrange into a crystalline shape when they freeze. That arrangement leaves more empty space between the molecules of water which reduces the density of the water in ice form. Lower density objects float on higher density liquids.

Answer 2

When water freezes, the weak hydrogen bonds between the molecules of water expand, lowering the density of ice and making it float. No matter how hard you try, unless a constant force is on top of the ice block, it will stay afloat at the water's surface.

Answer 3

because when water is frozen to make ice it expands, making it less dense and able to float

Answer 4

An ice cube is denser than air, or the other way around

Answer 5

Ice cubes do float on water.
