(Tuesday, 7:00 – 8:30 pm)

Meeting Topic: Talk by Steve Frankel on “Water: It’s a Deep Subject”

Outline:

1. Amphoteric Nature  – Water’s dual purpose as an acid or a base.
2. Cohesion & Adhesion  – Water is a sticky substance.
3. Density Anomaly  – Solid water (ice) is less dense than liquid water.
4. High Heat of Vaporization  – It takes an incredible amount of energy to turn liquid water into gas.
5. High Specific Heat  – Water absorbs a lot of heat before its temperature rises, helping regulate the Earth’s climate.
6. Polarity & Hydrogen Bonding  – The uneven sharing of electrons makes water polar (slightly negative O, slightly positive H).
7. Universal Solvent  – Its polarity allows water to dissolve many substances.

I may include some other information about this fascinating substance not included in the list above.
