Flashcards in Chapter 2: Water Deck (12):
1

-liquid water forms this
-each water molecule constantly break and reforms H bonds with its neighbors

water lattice

2

rigid crystalline structure in which each water molecule forms four H bonds, which spaces the water molecules farther apart

ice lattice

3

amount of heat energy required to increase the temperature of a given quantity of water

specific heat

4

allows humans and many other organisms to cool off when hot

heat of vaporization

5

water moderates on large and small scales

heat absorption

6

tendency of water molecules to "stick" to each other, due to H bond lattice

cohesion

7

tendency of water molecules to "stick" to the wals of tubes by forming H bonds with charged and polar groups in molecules that form the walls

adhesion

8

this unbalanced bonding paces the surface water molecules under tension making them more resistant to separation then the underlying water molecules
-water droplets

surface tension

9

tend to coat the surfaces of other polar and charged molecules and ions

hydration layer

10

hydration layers reduce attraction between molecules or ions and promote their entry into a _________

solution

11

water is a?

solvent

12

dissolved substance is a??

solvent
