Why is water freezing into ice a physical change?

Answer 1

You can always undo a physical change by reversing the process.

i.e. when you freeze water it turns into ice and when you heat the ice it turns back into water.

Therefore it is a physical change.

Answer 2

Water freezing into ice is a physical change because the molecules in water rearrange themselves due to a decrease in temperature, resulting in the formation of a solid structure (ice) with the same chemical composition as water. No new substances are formed during the process, making it a reversible change.

Answer 3

It is a physical change because water's chemical make-up hasn't changed.

Ice is still water and can then be changed back into its liquid form

and water can be refrozen to solid ice.

(A chemical change changes the substance to where it can't go back to its original, like burning wood or a leaf changing colors in the fall)
------------------------------------------------------------------------------------------

I'd have to say physical, because it still remains water or H2O. And does not change into another substance.

Answer 4

The basic property of ice is the chemical compound H2O. The chemical compound does not change while the ice melts, nor when the water evaporates. The chemical formula does not change. Therefore, it is a physical change of the compound, not a chemical change.

Answer 5

Changing the physical state of water from a liquid to a solid

Answer 6

because it is change in state from liquid to solid, and can be easily undone. A change that is easy to undo is physical.

Answer 7

Freezing water is a physical change because the end product is different. Freezing water is considered ice instead of water.

Answer 8

Yes, freezing water is a change of state, which is a physical change.

Answer 9

Water freezing is a Physical change because there is no Chemical reaction involved. It just a chemical (the water) changing from one state to another.

Answer 10

Because the structure remain the same.
