Question

As a substance changes fees from gas to liquid to solid :

A- the spacing between molecules increased
B- it’s density generally increases
C- the spacing between molecules is not affected
D- it undergoes a chemical change

Answer 1

it’s density generally increases

Step-by-step explanation:

Answer 2

I would say that the density increases because the distance between the molecules decreases, and therefore becomes smaller, and vice versa the density increases, and that is a physical change not a chemical change.
