When a substance changes form but it remains the same substance is it a chemical or physical change?
- it would be physical change because physical change is when the substance stays the same

What are the similarities between chemical and physical changes?
Both chemical and physical changes involve a transformation of matter. In physical changes, the substance's chemical composition remains the same, while in chemical changes, new substances are formed as a result of a chemical reaction. Both types of changes involve the absorption or release of energy.
What for a given substance never change?
A substance's chemical composition, which is determined by the types and arrangement of its atoms, always remains the same regardless of physical or chemical changes that may occur.
When gold changes from a solid to a liquid is that a physical or chemical change?
The change from a solid to a liquid is a physical change, as the substance's chemical composition remains the same. Physical changes affect the state or form of matter without altering its chemical composition.
Do chemical changes affect the chemical structure of a substance?
Yes, chemical changes result in a change in the chemical structure of a substance. During a chemical change, new substances with different chemical compositions are formed through the rearrangement of atoms and bonds. This is in contrast to physical changes, where the chemical structure remains the same even though the physical properties may change.
Are melting butter and melting ice cream are both physical change or chemical change?
They're both physical changes. Phase changes are always physical changes. Chemical changes only involve chemical reactions - a change in the identity of the substance. That's why phase changes are physical changes. Ice cream remains ice cream when it melts.
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.
Is copper sulphate a physical change?
Copper sulfate dissolving in water is a physical change because the chemical composition of copper sulfate remains the same. Physical changes do not alter the chemical structure of a substance.
What happens to a substance in physical change?
it means figure it out yourself!
What is called a change that does not make a substance into a new substance?
A change that does not make a substance into a new substance is called a physical change. In physical changes, the physical properties of the substance may change, such as shape, size, or state (solid, liquid, gas), but the chemical composition remains the same.
When matter changes in shape size or type but remains with the same substance?
That is a physical change. The chemical composition of the substance does not change during a physical change, only its physical properties like size, shape, or state of matter.
