We are told that there are solid and liquid phases of acetic acid, but the presence of an odor implies that there is a gaseous phase as well. It is likely that some of the acetic acid has vaporized due to its volatility. Therefore, there are 3 phases present in the bottle. The solid and liquid phases can be observed visually (the gas cannot since it is not colored), and the gas is detected because of its odor.
