- You drive a car on a winter day with the atmospheric air at -15 and you keep the outside frontwindshield surface temperature at +2 by blowing hot air on the inside surface. If the windshield is 0.5m 2 and the outside convection coefficient is 250 W/m 2 ·K, find the rate of energy loss (q) through thefront windshield. (hint: q=hA)arrow_forwardAdiabatic expansion produces a cooling , why?arrow_forwardDuring winter, when nights can be really cold, you will find that placing a large tub of water in a storage cellar would prevent food from freezing. Explain why.arrow_forward
- Why do you feel uncomfortably warm on a hot and humid day?arrow_forwardExplain why: (a) the earth without its atmosphere would be inhospitably cold(b) heating systems based on circulation of steam are more efficient in warming a building than those based on circulation of hot water.arrow_forwardIn warm regions where tropical plants grow but the temperature may drop below freezing a few times in the winter, the destruction of sensitive plants due to freezing can be reduced by watering them in the evening. Explainarrow_forward
- The reason for the preference of pilots to take off from the highest air port in the morning or the evening when the air is quite cold.arrow_forwardThe atmosphere of the planet Mars is 95.3% carbon dioxide (CO2) and about 0.03% water vapor. The atmospheric pressure is only about 600 Pa, and the surface temperature varies from -30°C to -100°C. The polar ice caps contain both CO2ice and water ice. Could there be liquid CO2 on the surface of Mars? Could there be liquid water? Why or why not? [please answer all questions. thank you]arrow_forwardYou can make rain in your kitchen. Put a cup of water in a Pyrex saucepan or a glass coffeemaker and heat it slowly over a low flame. When the water is warm, place a saucer filled with ice cubes on top of the container. As the water below is heated, droplets form at the bottom of the cold saucer and combine until they are large enough to fall, producing a steady “rainfall” as the water below is gently heated. How does this resemble, and how does it differ from, the way in which natural rain is formed?arrow_forward
- Near a large body of water, the fluctuations in air temperature are usuallyless extreme than they are far away from the water. Why?arrow_forwardOn a cold windy day, a window will feel colder than on an equally cold day with no wind. This is true even if no air leaks in near the window. Why?arrow_forwardOn average, would Earth be warmer or cooler without the atmosphere? Explain your answer.arrow_forward
