What happens when a pure substances undergoes a chemical change?
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped

Can a physical change change what a substance is Explain your answer by giving an?
No, a physical change does not change the chemical identity of a substance. For example, when water freezes to form ice, it undergoes a physical change in state, but it remains H₂O. The molecular composition stays the same, and the substance retains its chemical properties, regardless of whether it is in liquid or solid form.
What is the same about vaporization and sublimation?
in both , the substance involved undergoes a physical change
A substance that undergoes a chemical change is still the same substance after the change?

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 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.
How do the molecular energy molecular motion and overall mass of a substance change when matter changes state?
When matter changes state, the molecular energy generally increases as heat is added or decreases as heat is removed. Molecular motion increases as the substance transitions from a solid to a liquid to a gas. The overall mass of the substance remains the same throughout the phase change process, as no particles are added or removed.
What kind of change such as a change of state the substance of the whole changes but its underlying structure remains the same?
In changes in which the molecular structure of a substance remains constant, such as changes of state, we often refer to these changes as Physical Changes. If the molecular structure is altered it would be a Chemical Change.
When a substance undergoes a physical change its identity remains the?
When a substance undergoes a physical change, its identity remains the same, meaning its chemical composition does not alter. Examples of physical changes include melting, freezing, and dissolving, where the substance can typically return to its original state. The properties such as color, shape, and state may change, but the fundamental structure of the molecules remains intact.
What happens when a clear substnace undergoes a chemical change?
It is no longer that same substance. A chemical changes the identity of the substance. Individual atoms cannot be broken down into smaller parts by normal physical or chemical change.
