Problem
A particulate-level sketch shows 20 identical linear triatomic molecules of carbon dioxide packed closely together. In a second sketch, the same 20 intact molecules are spread far apart, but no new particle types appear. Is the change depicted physical or chemical? State the key evidence from the sketches that supports your answer.
