Chapter 2: Water

Question 1

• liquid water forms this

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

Answer 1

water lattice

Question 2

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

Answer 2

ice lattice

Question 3

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

Answer 3

specific heat

Question 4

allows humans and many other organisms to cool off when hot

Answer 4

heat of vaporization

Question 5

water moderates on large and small scales

Answer 5

heat absorption

Question 6

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

Answer 6

cohesion

Question 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

Answer 7

adhesion

Question 8

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

Answer 8

surface tension

Question 9

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

Answer 9

hydration layer

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

Answer 10

solution

Question 11

Answer 11

solvent

Question 12

dissolved substance is a??

Answer 12

solvent
