Question
Which example best describes a physical change?
- Iron rusting
- Charcoal burning
- An ice cube melting
- A marshmallow burning
Hint:
Physical change is a temporary change where the physical properties i.e. size, shape or external appearance of matter change.
The correct answer is: An ice cube melting
The melting of ice is a physical change.
- As an ice cube melts, its shape changes as it acquires the ability to flow.
- Here, only the state of matter i.e. water changes from solid to liquid.
- However, its composition remains the same. (does not change).
