Why does ice float in water? - George Zaidan and Charles Morton

Why does ice float in water? - George Zaidan and Charles Morton | WHS Chem Water | Scoop.it
Water is a special substance for several reasons, and you may have noticed an important one right in your cold drink: ice. Solid ice floats in liquid water, which isn't true for most substances. But why? George Zaidan and Charles Morton explain the science behind how how hydrogen bonds keep the ice in your glass (and the polar ice caps) afloat.

How polarity makes water behave strangely - Christina Kleinberg

How polarity makes water behave strangely - Christina Kleinberg | WHS Chem Water | Scoop.it
Water is both essential and unique. Many of its particular qualities stem from the fact that it consists of two hydrogen atoms and one oxygen, therefore creating an unequal sharing of electrons.

Density

Density | WHS Chem Water | Scoop.it
Density is a measure of mass per unit of volume. Density is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water). Perhaps the highest density known is reached in neutron star matter. The singularity at the centre of a black hole, according to general relativity, does not have any volume, so its density is undefined.

Why don’t oil and water mix? - John Pollard

Why don’t oil and water mix? - John Pollard | WHS Chem Water | Scoop.it
Salt dissolves in water; oil does not. But why? You can think of that glass of water as a big, bumpin' dance party where the water molecules are always switching dance partners -- and they'd much rather dance with a salt ion. John Pollard explains how two chemistry principles, energetics and entropy, rule the dance floor.
