Explanation:
Detailed explanation-1: -However, water has a unique property in terms of density. Its hydrogen bonds make solid ice less dense than liquid water and allow ice to float (Figure 4).
Detailed explanation-2: -Water is an excellent solvent. Water has the unique ability to dissolve many polar and ionic substances. This is important to all living things because, as water travels through the water cycle, it takes many valuable nutrients along with it!
Detailed explanation-3: -Summary. Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.
