Which of the following is not a property of water? Hydrogen bonding causes a high surface tension. Hydrogen bonds exist only in the solid state. Water can dissolve ionic and polar molecules. Water's solid state is less dense than its liquid state.

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
