The density of ice is lower than the density of water.
Since water expands when it freezes, it causes cracks in rocks when it freezes inside them.
they float because when water freezes its densitystays the same (1g/cm3) But the water particals spreadout makjng the ice less dense than the water.
Saturn. And then the water freezes...
It becomes less dense. Ice will float on water
Water freezes at 0 deg C. As the water freezes in the pipes, it expands and it is the force of expansion which causes the pipes to burst.
A cork has a low density. It is lower then water. That causes it to float.
The surface area of the raft displaces the water forcefully which causes float
It cracks the rock
What causes it to sink or float is the density. The density of water is 1.0. If the object's density is more 1.0 then it sinks, but if the object's density is less then 1.0 then the object will float.
when water freezes it expands therefor the water takes little space to take of a larger area then when it is placed in water it will float because it is less dense OR The simple, easy explanation: Water is one of the only liquids that expands when it freezes. Because it puffs up bigger when it's solid ice, it weighs less than water. And anything that weighs less than water will float on water like ice.
Its average density is a lot less than water
Expansion of water as it freezes ruptures the cell walls.
