Quizplus · Accepted Answer

All three statements about liquids are correct. Increased molecular motion does indeed result in an increased rate of evaporation because more molecules have enough energy to escape the liquid phase. Liquids take the shape of their container, distinguishing them from solids but not from gases. Lastly, liquids have relatively low compressibility compared to gases, as the molecules in a liquid are much closer together than in a gas, leaving less space to compress.
