An unusual fact of ice frozen at a pressure of one atmosphere is that the solid is some 8% less dense than liquid water. Therefore, water is one of the few substances to expand when it freezes. Ice has a density of 0.917 g/cm³ at 0 °C, whereas water has a density of 0.9998 g/cm³ at the same temperature. Liquid water is most dense, essentially 1.00 g/cm³, at 4 °C and becomes less dense as the water molecules begin to form the hexagonal crystals of ice as the temperature drops to 0 °C. (In fact, the word "crystal" derives from Greek word for frost.) This is due to hydrogen bonds forming between the water molecules, which line up molecules less efficiently (in terms of volume) when water is frozen. The result of this is that ice floats on liquid water, an important factor in Earth's climate. Density of ice increases slightly with decreasing temperature (density of ice at â180 °C (93 K) is 0.9340 g/cm³).
When ice melts, it absorbs as much heat energy (the heat of fusion) as it would take to heat an equivalent mass of water by 80 °C, while its temperature remains a constant 0 °C.
It is also theoretically possible to superheat ice beyond its equilibrium melting point. Simulations of ultrafast laser pulses acting on ice shows it can be heated up to room temperature for an extremely short period (250 ps) without melting it. It is possible that the interior of an ice crystal has a melting point above 0 °C and that the normal melting at 0 °C is just a surface effect. [1]
As a naturally occurring crystalline solid, ice is considered a mineral.
The smallest ice was created by Roger Miller and Klaus Nauta in the University of North Carolina in 1999. It is 6 water molecules arranged in a hexagon, theoretically the smallest ice possible.

ice and water both of them are the same
water when cooled becomes ice
and ice when heated becomes water

Ice, then if you want water just let the ice melt

Water, but I like ice sometimes, like when I'm bored....
