YOUR TEST NUMBER IS THE 5-DIGIT NUMBER AT THE TOP OF EACH PAGE. (1) Please print your name and your UF ID number and sign the top of this page and the back of the answer sheet. (2) Code your test number on your answer sheet (use lines 76–80 on the answer sheet for the 5-digit number) . (3) This is a closed book exam and books, calculators or any other materials are NOT allowed during the exam. (4) Identify the number of the choice that best completes the statement or answers the question. (5) Blacken the circle of your intended answer completely, using a #2 pencil or blue or black ink. Do not make any stray marks or the answer sheet may not read properly. (6) Do all scratch work anywhere on this printout that you like. At the end of the test, this exam printout is to be turned in. No credit will be given without both answer sheet and printout. There are 40 multiple choice questions. All questions are worth 2.5 points, so the maximum number of points on this test is 100. If more than one answer is marked, no credit will be given for that question, even if one of the marked answers is correct. There is no penalty for wrong answers, so it is better to guess an answer than to leave it blank. Good Luck! 1. On a cold foggy day, when the relative humidity is 100%, water vapor occupies about what percentage of the air’s volume near the earth’s surface? (1) less than 4% (2) about 78% (3) about 21% (4) almost 100% (5) about 50% 2. Which of the following is most likely associated with fair (i.e. clear and sunny) weather? (1) a high surface pressure area (2) a low surface pressure area (3) a cold front (4) a warm front (5) an occluded front 3. How many of the phase changes indicated by the arrows in the figure release energy to the surroundings? (1) one (2) none (3) two (4) all three (5) — 4. Assuming that the night will remain clear, calm, and unsaturated, the predicted minimum temperature is 32 ◦ F. Suddenly the wind speed increases and remains gusty throughout the night. The minimum temperature will most likely be: (1) higher than predicted due to mixing (2) about the same as predicted, but will occur earlier in the night (3) about the same as predicted, but will occur later in the night (4) higher than predicted due to the release of latent heat (5) much lower than predicted due to radiational cooling 5. Suppose saturated polar air has an air temperature and dew point of- 10 ◦ C, and unsaturated desert air has an air temperature of 35 ◦ C and a dew point of 10 ◦ C. The desert air contains water vapor and has a relative humidity than the polar air....
