A solid is dissolved in a liquid, and over time a solid forms again. How can

you confirm the type of change that took place?

A. Testing the new solid to show that its properties are the same as

the starting solid would confirm that a physical change took

place.

B. The solid dissolving in a liquid is confirmation that a chemical

change took place.

C. The solid forming from the liquid is confirmation that a physical

change took place.

D. Showing that the total mass of the solid and liquid changed would

confirm that a chemical change took place.
