Problem

At 25 °C a pure substance is examined at the molecular level. The molecules remain in continuous contact, frequently breaking and reforming hydrogen bonds, and the sample maintains a fixed volume while adopting the shape of its container. Which substance below is most likely in the physical state described? (a) CH4(g)\text{CH}_4(g) at 25\,°C (b) Hg(l)\text{Hg}(l) at 25\,°C (c) H2O(l)\text{H}_2\text{O}(l) at 25\,°C (d) H2O(s)\text{H}_2\text{O}(s) at -10\,°C
