A substance that undergoes a physical change is water when it freezes into ice. This process changes the state of the water from liquid to solid without altering its chemical composition. Similarly, when ice melts back into water, it undergoes another physical change. Other examples include the melting of wax or the dissolving of sugar in water.

How do chemicals differ from physical changes?
When matter undergoes a chemical change, the composition of the matter changes. When matter undergoes a physical change, composition of the matter remains the same.
This is the rate at which a substance undergoes a chemical change?
This is called reaction rate.
What happens to a substance in physical change?
it means figure it out yourself!
When a substance dissolves it undergoes a chemical change physical change molecular change?
When a substance dissolves, it undergoes a physical change, not a chemical change. This is because the molecules of the solute are dispersed in the solvent but do not undergo any chemical reactions. The process of dissolving is a result of the attraction between the solute and solvent molecules.
Melting a sugar cube is what kind of change?
Melting a sugar cube is a physical change because the substance undergoes a change in state from solid to liquid without altering its chemical composition.

Does a physical change make the substance that undergoes it a different substance if not then what can change?
After a physical change a substance does not change its chemical composition it simply changes its state as, water to ice or vapours.
Do intrinsic or intensive properties of a substance change when it undergoes physical change?

Are there changes in the chemical changes of a substance when it undergoes a physical change?
nada
When a substance undergoes a physical change what does not a change?
The chemical make up of a substance does not change. It must remain the same combination of atoms or molecules to be considered only a physical change.
What is the same about vaporization and sublimation?
in both , the substance involved undergoes a physical change
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.
The expansion of matter upon heating is an example of what change?
The expansion of matter upon heating is an example of a physical change. This is because the substance undergoes a change in form or appearance without forming a new substance.
