which change is the best example of a physical change?
There are multiple examples, for instance:
- Cutting a paper - Ripping an object - Mixing sand and water
Basically, anything that changes an object but is able to be reverted back to its original form. Since physical change is the opposite of chemical change, you need to focus on the factor that physical change keeps its original form.
A chemical change is when you can't revert the object back to its natural form, for instance, burning a paper or lighting anything on fire.
