because it freezes
When water freezes, it turns into what we call ice. ice is a solid. no offense, but um stupid question.
Hot Water
When water freezes at 0 degrees Celsius, it undergoes a physical change. This is because the molecules in water rearrange themselves into a solid structure without any change in their chemical composition.
Freezing is a physical change.
when water freezes, it becomes a solid, it's called 'Ice'.
Fresh water freezes at 32°f (0°c) at sea level. Sea water freezes at 28.4°f (-2°c) at sea level. Salt water depends on the concentration of salt. At maximum saturation salt water (23.3% by weight) freezes at -5.98°f (-21.1°c).
This is a physical change. It's still water, just in solid form.
Physical!Ice is H20(s) and Water is H2O(l)
The volume of a kilogram of water will decrease when it freezes. This is because water expands as it freezes, leading to a larger volume of ice compared to the same mass of liquid water.
It does what all water does when it freezes: expands. This will crack the rock.
