Liquid nitrogen has different properties from gaseous nitrogen. Is it a chemical change when liquid nitrogen warms to gaseous nitrogen?

Question

Yes, because chemical changes result in different properties.
No, because chemical changes do not result in different properties.
No, because the different properties are physical while the chemical properties remain the same.
Yes, because warming is a chemical change even though the physical properties remain the same.

Answer 1

The correct answer is: No, because the different properties are physical while the chemical properties remain the same.

When liquid nitrogen warms up and changes to gaseous nitrogen, this is a physical change, not a chemical change. The substance remains nitrogen throughout the process; only its state (from liquid to gas) changes. The chemical properties of nitrogen remain unchanged.
