Condensation of water vapor on a bathroom mirror is classified as a physical change. Which of the following best explains this classification?
a) The process is reversible under standard laboratory conditions.
b) The chemical formula changes from H2O(g) to H2O(l), indicating a chemical change.
c) Only intermolecular forces are altered; the covalent O−H bonds within each H2O molecule remain intact.
d) Energy is absorbed from the surroundings rather than released during the process.
