Does what happens to a gas and a liquid regarding molecular motion also happen to a solid? What if we heat and cool a solid? How does it change, if at all?
We're working through our reasoning to this phenomenon and we're discovering many things. We still have questions about how we smell an odor though since we don't see all solids melt, and we recognize we smell something b/c there must be a gas particle in the air. It's getting us thinking for sure!
