Ice from liquid water only involves a physical change, not a chemical change.
As liquid water cools, the energy removed from the system allows a crystalline matrix to start forming between the partially charged molecules as there's no longer enough energy to break hydrogen bonding, resulting in the increased volume (and thus, lower density) of ice.
However, no other chemicals are added or produced from the reaction. It purely depends on the energy of the system.
physical change
I do not really care
no
yes
It is PHYSICAL because when the ice cubes melt, they turn into water. We can reverse the change and bring the water back into ice. Water has a chemical formula of H2O and so does ice. So, Physical Change: can be reversable, the object's components don't really change.
well when water changes into ice its a form of physical change
It's a physical change.. it can go back to the way it was before.
It is a physical change. :D
There are 2 types : chemical change and physical change the substance has changed state, you can see the change so basically its visible
Physical change
Physical change
No. It is a physical change.
Dissolving salt in water and making ice cubes
No, it is a physical change, not a chemical reaction.

Its a physical change because it can be reversed by re-freezing the water.
Yes , you have a liquid turning into a solid .
no its a chemical change (i just did i project on making ice cream in meh class and one question was "is this a chemical or physical change? how do u know?"
