Question

A copper part is heated. Does its mass, volume and density change?

Answer 1

Heating copper in its elemental form is a physical change. The mass of any substance does not change during a physical change, so the mass of copper will stay the same. However, its volume will increase, so its density will decrease

Step-by-step explanation:

Answer 2

It's volume and density will increase but NOT the mass

Step-by-step explanation:

Heating copper in its elemental form is a physical change.

The mass of any substance does not change during a physical change, so the mass of copper will stay the same. However, its volume will increase, so its density will decrease.
