no. same weight, lower density.
same weight because it's still the same amount of water.
lower density because air bubbles are traped inside the ice and make it expand... same mass, bigger volume --> lower density.
to prove it's the same weight, then take a glass of water and put an icecube in it. and put everything on a balance. wait for the ice to melt : you'll se the weight won't change.
to prove it has a lower density than water, put an ice cube in water and watch it float.

No its the same weight but expands, so it becomes less dense. Because it is less dense than water it then floats. If it shrunk or became heavier, it would sink and we wouldn't exist cos earth would be too cold. Ie sun can't melt the ice. Oddly enough water is the only substances that expands when frozen, most expand when heated and contract when cooled. Coincedence or design?

No it gets lighter and expands to form an open lattice structure. Air can get between the molecules of water and thus ice floats because it is less dense than water.
Water really is quite an amazing substance when you think about it!

Just above the freezing point, water is still a liquid. When it freezes it forms a lattice structure which takes up more space than the nearly-frozen liquid. But as it continues to cool, the lattice structure gets denser, eventually denser than the nearly-frozen liquid.

No, it doesn't. It gets "lighter" by changing it's density... this means that the weight is exactly the same, but the distance between the H2) molecules is bigger, hwich makes it less dence than water, which makes ice float on water.

Water is the only substance that gets larger as it gets colder. The molecules of ice and snow are larger than that of water.

Water actually gets heavier at 4 degrees centigrade, at lower temps or higher temps it is lighter. when it freazes it gets less dense.

Ice is cold and condenses water form the atmosphere at normal temperatures.

because the density of water is the highest at4 deg.C and below this temp.the density decreases.this phenomenon is called the anomalous expansion of water and saves the aquatic animals in winter

No It becomes less dense that is why ice floats on water.
