Quick road side stop and grab
South Africa is a very water scarce country. These little farm dams offer relief not only to the cattle that is farmed with but also the wildlife of the area.
Do some bird watching while you are stopped.
Hydrogen bonds
Hydrogen bonds form between the Hydrogen atoms or water molecules. These hydrogen bonds are exceptionally strong and give water its high boiling point, and low freezing point. Very simply put.
The boiling and freezing points of water - 100 degrees Celsius and 0 degrees Celsius respectively - are used as common standards in many other Physical Chemical calculations.
