Problem
A student records the following observations for eight separate processes carried out at constant pressure in the laboratory.
(a) Sort the eight processes into two groups—those that represent chemical changes and those that represent physical changes—based solely on particulate‐level reasoning. Present your answer in a clearly labeled table.
(b) For ONE process you identified as a chemical change and ONE process you identified as a physical change, explain your classification in terms of what happens to intramolecular bonds and intermolecular forces.
