Problem

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)\mathrm{H_2O(g)} to H2O(l)\mathrm{H_2O(l)}, indicating a chemical change. (c) Only intermolecular forces are altered; the covalent O−H\mathrm{O{-}H} bonds within each H2O\mathrm{H_2O} molecule remain intact. (d) Energy is absorbed from the surroundings rather than released during the process.
