1. Water
It’s important.

2. Water
It’s the first in a list of molecules we study. Let’s look at it:
Fascinating. But this simple structure gives it some interesting properties.

3. What’s so amazing about water?
Oxygen likes electrons, it likes them lots.
Hydrogen doesn’t really care.
So one end has more electrons than the other.
Who cares?

4. They’re all sticky!
Water molecules will stick together, holding on to each other. This makes them hard to move.
This attraction between a slightly (δ) negative Oxygen and a slightly (δ) positive Hydrogen is called:
Hydrogen Bonding

5. What’s the big deal? High Specific Heat Capacity
High Latent Heat of Vapourisation
Universal Solvent
Surface Tension
High Density
Little creatures can walk on it!
It dissolves lots of things
You can float in it
It doesn’t dry up too quickly
Stays at a constant temperature.
