A:
Freezing water is changing the state of matter, not the chemical composition of it. Look up the term electrophoresis It will explain what happens during this process (it does change the chemical makeup of water by moving electrons and such)

∙ 12y agoWhen water freezes, it is still made up of water. This is not a chemical change.
H2O(l) --> H2O(s)
When water undergoes electrolysis, water is destroyed, and hydrogen and oxygen gas are produced. This is a chemical change.
2H2O(l) --> 2H2 + O2

Is freezing point physical property a physical change a chemical property or a chemical change?
Freezing point is a physical property. The actual freezing is a physical change.
What type of change is freezing water?
Freezing water is an example of a physical change because the material contents of the water has not changed.
Is water freezing at 0 degrees a physical change?
Freezing is a physical process.
Is freezing nitrogen gas a chemical change?
No. Freezing a substance is a physical change.
Does freezing Lauric acid undergo a chemical change?
No, it undergos a physical change
Why is the electrolysis water classified as a chemical change but the freezing of water is not?
Freezing is a phase transition and does not change the chemical makeup of H2O. (melting restores). Electrolysis changes the chemical structure of the water, decomposing the H2O into oxygen (O2) and hydrogen gas (H2).
Is freezing a physical change?
yes freezing is a physical change.
Is freezing point physical property a physical change a chemical property or a chemical change?
Freezing point is a physical property. The actual freezing is a physical change.
Is the freezing of H2O a chemical or physical change?
Freezing of H2O is a Physical Change.
What type of change is freezing water?

Is freezing nitrogen a chemical change?
No. Freezing a substance is a physical change.
Why is freezing a physical property?
Freezing is a physical change because the substance that freezes does not change its chemical composition.
Is a freezing point a chemical change or physical change?
It is a physical change.

Physical Change
Is freezing point a physical property a physical change a chemical property or a chemical change?
I believe it is physical because you are not changing the chemical compound.
