5. Dihydrogen Monoxide What is it?

6. Dihydrogen Monoxide Water

7. Water Dihydrogen monoxide is the chemical name for the most common compound on the planet.

8. Water Water’s unique properties allow life to occur. They include: • high specific heat- heats slowly and cools slowly

9. Water Water’s unique properties allow life to occur. They include: • High specific heat- heats slowly and cools slowly • Liquid phase is more dense than solid phase • Water can exist as a gas, liquid and solid at the same time

10. Water Water’s unique properties allow life to occur. They include: • High specific heat- heats slowly and cools slowly • Liquid phase is more dense than solid phase • Water can exist as a gas, liquid and solid at the same time • Considered the universal solvent

11. Water These properties are due to water’s polar nature.

12. Water These properties are due to water’s polar nature. This is due to the unequal sharing of electrons.

13. Water These properties are due to water’s polar nature. This is due to the unequal sharing of electrons. The result is the water molecule has a positive and a negative end.

17. Water • Hydrogen bonding explains water’s unique properties including: • Surface tension • Cohesion • Adhesion

18. Surface Tension Surface tension is the attraction of water molecules at the surface . It is responsible for the meniscus seen in a graduated cylinder.

19. Cohesion This term is used to describe water molecules sticking to each other. This is used to describe surface tension.

20. Adhesion This term describes how easily water molecules stick to other surfaces. How easily does something absorb water.

21. Adhesion Does this have a low or a high cohesive force?
