A physical change occurs when substance undergoes a physical change, it does not give rise to a different kind of substance or there is no new substance is formed.
- For example : heating of water , melting of butter, cutting of paper and etc.
Answer:
A physical change occurs when the temperature or form changes but not the actual substance itself.
Explanation:
If a substance's physical form changes, such as it's temperature, then it's a physical change. Another way of finding out if it's a physical change is if it's not a chemical change and it still changes. A chemical change happens when the substance changes in a molecular way. For example, when the lady of liberty was exposed to air over time, the brown copper turned green. This is where the substance actually changes. Hope this more in depth explanation helps:D
