Ana amount of nitrogen undergoes a physical change and increases its volume. What can be known about this physical change

A.) the boiling point
B.) the mass of nitrogen increased
C.) the color change
D.) the density changed

D.) the density changed

Explanation:

This would be the answer because it is a specific amount of Nitrogen undergoing a physical change. Since the color and boiling point don't influence a change in volume, those are ruled out. Also, nitrogen's molecular mass never changes, so that would not make sense either. But if the density, which is mass/volume, has changed (more specifically decreases) then it means the volume has increased.

Hope this helps.
