Fifteen grams of a liquid plastic are frozen in a physical change that increases the volume. what can be known about the plastic after the change?

it will weigh more than 15 grams.
it will have an increased density.
it will still weigh 15 grams.
it will still have the same density.

I believe the correct answer from the choices listed above would be the third option. Fifteen grams of a liquid plastic are frozen in a physical change that increases the volume. After this change, we can still say that it will still weigh 15 grams. This is on the basis of the law of conservation of mass where mass cannot be destroyed nor created.
