|
Water molecules stick together by cohesion.
|
|
|
Frozen water is less dense than liquid water.
|
|
|
Water molecules stick to other polar substances.
|
|
|
Hydrogen bonds allow water to heat and cool very quickly.
|
Detailed explanation-1: -So, the correct answer is ‘It becomes more dense when it freezes’.
Detailed explanation-2: -The statement that water becomes denser when it freezes is not a property of water.
Detailed explanation-3: -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.
Detailed explanation-4: -Which of the following is not a property of water that results from hydrogen bonding? Water has a high surface tension.
Detailed explanation-5: -Water is the universal solvent. Exists in nature as a solid, liquid, and gas. The density of ice is less than liquid water. Water has a high heat of vaporization. More items •23-Sept-2021
