Nearly, a physical change creates a substance and this is reversible. For example, ice-water. Water-steam. These are all reversible. A chemical change is irreversible. For example, baking a cake; you cannot get the original ingredients back again.

A physical change that does not produce a new substance is called what?

A physical change that does not produce a new substance is called a reversible change. This means the change can be undone by reversing the process, such as melting or freezing.


What does it mean to say a physical change is reversible?

A physical change is reversible if the substance can return to its original state after the change has occurred. This means that the change does not alter the chemical composition of the substance, allowing it to be reversed through processes like melting, freezing, or evaporation.


What is the substance that undergoes a physical change but always stays the same?

a physical change is totally reversible, i.e, you can get the substance you will get back after some physical process like heating, evaporating, etc. thus the substance actually remains the same.


What type of change is freezing?

Freezing is a physical change in which a substance transforms from liquid to solid state by losing heat energy. It is a reversible process.


Is cutting your fingernails physical or chemical change?

What is important is physical change?

The importance of physical change is that :-1) No new substance is formed.2) It is a temporary change.3) It is easily reversible.4) Very little heat energy is absorbed or given out.The mass of a substance does not alter in a physical change.

Is freezing a physical change?

Yes, freezing is a physical change because it is a reversible process where a substance changes from a liquid to a solid state without changing its chemical composition.


What is the difference between chemical change and physical change?

the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
