it would be physical change because physical change is when the substance stays the same
When a substance changes into a different substance a blank change has occurred?

What kind of change happens when the composition of a substance does not change?

The expansion of matter upon heating is an example of what change?

How are a chemical and physical change different?
In a physical change, the substance is still the same substance after the change. But in a chemical change, the substance became another substance with different properties from the original substance.Physical change is changing the appearance of something.

Can a physical change change what a substance is?
a physical change will only alter the appearance but will NOT change the substance to another substance =)
