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 to form a ice a chemical change?
No, freezing is not a chemical change. It is a physical one. It (freezing) is reversable, and the substance that is changing state to a solid or from a solid is not undergoing any chemical changes.
Is water freezing at zero degrees Celsius physical or chemical change?
Physical. Ice is simply the solid form of water. If it were a chemical change, then ice would not be water.
Why is the electrolysis of water is classified of physical 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 ice cubes forming in the freezer a chemical reaction?
No, freezing water is a physical change, not a chemical one since no chemical reaction takes place. The water molecule (H2O) remains the same even though the physical state changes from a liquid to a solid.
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 juice freezing a chemical change?
No, it is only a physical change since the chemical properties of alcohol do not change.
Water freezing physical change or chemical change?

Is it a chemical change if the water begins to freeze?
Freezing is a physical change.
Is water freezing and forming physical change or chemical change?
physical
Is a substance freezing a chemical reaction?
No, freezing water is not a chemical reaction. It is a physical change which water undergoes at temperatures below 0oC. At higher temperature the ice melts back to water again.
What change is freezing water?
Physical change, seeing as how none of the chemical makeup of the water is changed.
Is movement a chemical change?
No, That would be a physical change....A chemical change would be for like example: Water Evaporting, Water Boiling, Water Freezing...etc

Is cooling liquid water to form ice a chemical change?
No. Freezing is a physical change.
Water freezes at o degree chemical or physical change?
Freezing is a physical change.
What change is freezing?
Physical change, seeing as how none of the chemical makeup of the water is changed.
