Question 7 Which of the following is a reason why we shouldn’t be surprised that the climate in San Francisco is much milder than that of Washington, D.C., even though they are at about the same latitude and are both close to the ocean? Answer a) because San Francisco is mountainous and is protected from changing climates whereas Washington, D.C., is flat and more susceptible to the weather b) because San Francisco is in California, which is more of a desert climate (and warmer), whereas Washington, D.C., is part of a humid, forested climate c) because San Francisco has the benefit of ocean air moving across it, whereas Washington, D.C., gets air from land that has a lower specific heat capacity than does wet air d) because San Francisco is elevated above the ocean and Washington, D.C., is completely at sea level 2 points Question 8 You are heating crushed ice and a small amount of water and monitoring the temperature of the icy slurry until it reaches the point were the ice is nearly melted. How does the temperature change during this process? Answer a) The temperature drops as the ice absorbs the heat and liquefies. b) The temperature stays at exactly 100°C. c) The temperature stays at constant throughout. d) The temperature goes up sharply as you heat the icy water. 2 points Question 9 Capillary action and the resulting meniscus of liquids in a small glass tube is due to: Answer a) cohesive forces. b) adhesive forces. c) interplay of adhesive and cohesive forces. d) strong adhesive and weak cohesive forces. 2 points
