Ice turn in water only if the temperature is over 0 0C.
Freezing point of water
Because the water molecules 'lock' together when the temperature drops - forming solid ice. Warming up the ice-cube releases the 'lock', and the ice turns back to water.
Because it changes from a solid shape (ice cube) to a liquid shape (Water)
It changes from a solid to a liquid.
When ice cube is submerged on water...The upthrust created on the ice cube by water is equal to the weight of the displaced water...when the ice cube is melting its volume changes but its weight remains the same and its exactly equal to the weight of displaced water when the ice cube was frozen...therefore the 'volume of of melted water' fits exactly to the 'volume of displaced water when the ice cube was frozen'... So the water level does not change! -Shenal K Mendis ;)
The weight of the water will stay the same whether ice, water or steam, because the mass has not changed.
Melting is a physical change.
