(08.01 LC)
Frozen water is less dense than liquid water, allowing lake organisms to survive winter. (3 points)

True
False
Question 2 (3 points)
(08.01 LC)
Which of the following is a correct statement about water? (3 points)

a
Hydrogen bonding causes water to be strongly cohesive.

b
Hydrogen bonding causes water to have a low surface tension.

c
Water is a universal solvent because polar and nonpolar solutes can dissolve in it.

d
Water is less dense as a liquid than as a solid because of changes in bond structure.

Question 3 (3 points)
(08.01 LC)
What change would increase the amount of solid solute able to be dissolved in liquid water? (3 points)

a
Decreasing rate of stirring

b
Decreasing surface area

c
Increasing pressure

d
Increasing temperature

Question 4 (3 points)
(08.01 MC)
Why is oil unable to dissolve well in water? (3 points)

a
Oil molecules are too large to fit between the closely spaced water molecules in the liquid state.

b
Oil is less dense than water, which means oil and water are not compatible for mixing together.

c
Water has strong cohesive properties, so polar oil is unable to pull the water molecules apart.

d
Water is polar and oil is nonpolar, which means water and oil have no attraction for each other.

Question 5 (3 points)
(08.01 MC)
Which of the following describes an impact of the specific heat of water on the planet and the life forms that exist on it? (3 points)

a
Places near the sea show high temperature variation.

b
Inland cities have moderate temperatures throughout the year.

c
Marine life experiences sudden spikes and drops in temperature.

d
Sweat requires a lot of thermal energy to be absorbed to evaporate.
