The ice float on water because the density of ice is lower (0,916 7 g/cm3 at 0 0C) than the density of water (o,999 8 g/cm3 at 0 0C).
The density of the floating cube is equal to the density of the fluid it is floating in. This is because the cube is in equilibrium, meaning the weight of the cube is equal to the weight of the fluid it displaces. Therefore, its density is the same as the fluid's density.
That would be an ice cube.
It would eventually melt, and somewhat cool the water.
Let V be the volume of the ice cube and U be the volume of the cube immersed in water density of water at 4oC = 0.998 g/cm³ density of ice at 0oC = 0.917 g/cm³ Weight of the ice cube = volume * density * g = 0.917*V*g [N] Buoyancy on the ice cube = volume * density * g = 0.988*U*g [N] Apply Newton's 3rd Law of Motion to the floating ice cube: 0.917*V*g = 0.988*U*g U/V = 0.928 = 92.8% Hence, 92.8% of the ice cube is immersed in water, or 7.2% of the ice cube is above water. The answer in percent can be converted to a fraction as follows: 7.2/100. =========================
Ice have a tetrahydral shape and this shape causes greater empty spaces in ice because of these empty spaces, ice usually occupies 9% more volume than water.Empty spaces reduces the density of ice and ice starts to float on the surface of water.
Its actually quite simple. The answer would be Anomalous expansion of Water, which means that the volume the Ice cubes are consuming in a glass filled upto the brim is more than water alone. When Ice melts and comes back into water form, it uses lesser volume (space) in the glass. Hence it does not allow the glass to overflow as the person pouring into the glass had poured in keeping into view the level of the ice (which uses more volume).
The water level will decrease slightly when the ice cube melts, but the overall volume will remain constant. The melted ice will just fill the space that the ice cube previously occupied, so the glass will not overflow.

An ice cube will dissolve in water because the water is warmer than the ice.
Ice is a solid and water is a liquid, so an ice cube floating in a glass of water would be a solid in a liquid solution. Lava is molten rock, which would also be a solid in liquid solution.

It will melt.
The water level remains the same after the ice cube melts because the volume of the ice cube is already accounted for in the water level when it is frozen. When the ice melts, it simply changes state from solid to liquid without changing the overall volume in the glass.
by keeping it in a glass of water and by keeping it out
That would be an ice cube.
by keeping it in a glass of water and by keeping it out
The water level lowers. See the Related Question below for additional info.
