Which among these is defined as a physical change?
- It’s when a transformation doesn't change the nature of the molecules in matter
- It’s when a transformation change the nature of the molecules in matter
- It’s when a transformation change the nature of the molecules in substance
- All of these
Hint:
A change in which a substance undergoes a change in its external, physical properties such as shape, size, color, and state is called a physical change.
The correct answer is: It’s when a transformation doesn't change the nature of the molecules in matter
When a transformation doesn't change the nature of the molecules in the matter is defined as a physical change.
- A physical change is generally reversible,(with some exceptions).
- In a physical change, no new substance is formed and there is no change in the nature of the substance.
