Bermuda is close to North Carolina, but unlike North Carolina it has a tropical climate year round. Why is this so?
A) Since North Carolina is so humid, much of the sun's energy is absorbed by the water in the air, which has a high heat capacity.
B) North Carolina has a much higher elevation than sea level, keeping the state cool.
C) Since Bermuda is surrounded by water, its temperatures are moderated by the high specific heat of water. When the air is cooler than the water, the water warms the air; when the air is warmer than the water, the water cools the air.
D) The winds blow from the west, cooling North Carolina, but they blow from the east over Bermuda, which causes the tropical climate of that island.
Question 2
When water freezes, it expands. What does this say about the density of ice compared with the density of water?
A) The density of water and ice are identical since they have exactly the same chemical formula.
B) The expansion of water when it freezes to ice changes its volume, not its density.
C) Ice is less dense than water because it has more volume for the same mass.
D) Ice is more dense than water because it has more volume for the same mass
