Question

Which is an unusual property of water? `"1. The gas has a smaller volume of than the liquid."` `"2. The density of the solid phase is LESS than the liquid phase."` `"3. It has a molecular mass of "18.01*g*mol^-1;` `"4. The"` `H-O` `"bonds are weak."`

Answer 1

`"Number 2"`

Explanation:

Water is an extraordinary substance. For such a small molecule, it has an extraordinarily high melting and boiling point. And its peculiarity is to be explained by hydrogen bonding, which acts as a potent intermolecular force.

The most extraordinary property with regard to liquid water is that water as a LIQUID is more DENSE than water as a SOLID, whereas most solids are DENSER than their liquid phases. Hence ice cubes float......on top of your cocktail, or on top of the ocean. And thus we choose `"option 2"`.

What hazard does this property pose to passenger liners?
