Water freezing from liquid to solid is a reversable process, which mean it can be un-done, but a chemical reaction is when one or more objects react together to create something new which cannot be reversed. So when you mix vinigar with bicarbonate of soda try reversing the foam it creates!

Is it physical or chemical when water freezes at 0 degree celsius?

When liquid water freezes to form ice, the chemical composition of water does not change. It will be H2O whether it is in liquid state or solid state. So it is a physical change and not a chemical change.


Does ice undergo a chemical change when it freezes?

No, ice does not undergo a chemical change when it freezes. Freezing is a physical change that causes water molecules to slow down and come closer together, forming a solid structure with the same chemical composition as liquid water.


Is liquid water freezes in solid ice is it a chemical change or physicals?

Physical - it is still H20, frozen or not.


Is freezing point physical property a physical change a chemical property or a chemical change?

The freezing point is a physical property because it describes a characteristic of a substance (temperature at which it freezes) without changing the chemical composition of the substance. When a substance freezes, it undergoes a physical change from a liquid to a solid, not a chemical change.


Does liquid lose chemical energy when frozen?

No, when a liquid freezes, it undergoes a phase change from liquid to solid but does not lose chemical energy. The energy required for freezing is used to reorganize the molecules in the liquid into a solid structure, but the chemical energy of the molecules remains the same.


When does A liquid changes to a solid state at its?

A liquid will change to a solid when it freezes.


When water is put in the freezer to make ice is it a physical change or a chemical change?

A physical change.


Is making ice candy physical or chemical change?

Physical change because the strawberry is still a strawberry and the chocolate is still chocolate.


Is mixing elmers glue and liquid starch a chemical change?

No, mixing Elmer's glue and liquid starch is a physical change. A chemical change involves the formation of new substances with different chemical properties, while mixing these two substances does not result in a chemical reaction.


When something freezes does it change composition?

When a substance freezes, its physical state changes from liquid to solid, but its chemical composition remains the same. For example, water freezes into ice, and both have the same molecular structure (H2O). However, the arrangement of molecules changes, affecting properties like density and rigidity. Thus, while the form changes, the underlying chemical identity does not.


When liquid becomes a water vapor is that a chemical reaction?

no. chemical reaction requires a new substance to be created


How does a solid change from a solid to a liquid?

When water freezes it changes from a liquid to a solid. When water boils or evaporates it changes from a liquid to a gas.
