28. Humidity equals the amount of water vapor in the
air. Relative humidity equals the amount of water
vapor that can still enter the air mass before it
becomes saturated.
29. Transformed — heat energy can be absorbed or
reflected by clouds or dust in the atmosphere; it can
be absorbed by the Earth and converted into heat
energy. Transferred — conduction, convection,
advection, radiation.
30. 64°F
31. a. A new car door makes an airtight seal. As the
door is closed, air is compressed and can not escape.
Thus,the door will not close securely because of
greater pressure inside.
b. The “pop” is caused by a tube behind the eardrum
adjusting to the change in atmospheric pressure.
c. When you punch one hole in the can, the liquid
does not flow out readily because a partial vacuum
is produced. When you punch a second hole, the air
enters the top hole and the liquid flows out the bottom
hole. No partial vacuum

29. It is safer to fly on the windward side which has little
turbulence. The leeward side will most likely have the
turbulent downdrafts.
30. None. The rotor clouds will form on the leeward side.
