Complete the statements based on water’s polarity and ability to form hydrogen bonds. water’s boiling point is abnormally than expected. water has a surface tension, allowing adhesion, cohesion, and capillary action. water has a capacity to retain heat, keeping moderate climates warmer in the winter. water as it freezes, so ice floats when expected to sink. answers are higher high high expands
