Chapter 05 Quiz

Question 1)The specific heat of ice is half that of liquid water. Therefore, if 1 calorie of heat is required to raise the temperature of 1 g of liquid water by 1 Celsius degree, how much heat is required to raise the temperature of 1 g of ice by 1 Celsius degree?

Question 2

The reason it takes so much heat to melt ice or evaporate water is that extra energy is required to break

                   bonds between water molecules.

Question 3

A mechanism involved in the transfer of gases at the air-sea interface is known as                .

Question 4

Of the more than 70 different ions that are dissolved in seawater the two most abundant             

Question 5

When liquid water vaporizes (i.e., evaporates, sublimates, boils), enough latent heat is absorbed to essentially                      .

Question 6

Water exists in all three phases (solid, liquid, and vapor) on Earth's surface because of the presence of

                   bonds.

Question 7

Density of seawater is controlled primarily by                  .

Question 8

Sea ice, formed when seawater freezes, contains                   salt than seawater.

Question 9

Ocean acidification is accompanied by a(n)                   in pH.

Question 10

The density of seawater of average salinity (about 35) varies                with temperature.

Question 11

                   ice dominates the Southern Ocean around Antarctica.

Question 12

In surface ocean waters, the most abundant dissolved gases are:

Question 13

The average kinetic energy of water molecules                 .

Question 14

In the photic zone, the concentration of dissolved                  is higher relative to dissolved

                  .

Question 15

Fresh water begins to freeze at                 .

Question 16

Liquid water changes to a vapor via                  .

Question 17

When seawater evaporates, all dissolved salts                   .
