QUIZ 2 REVIEW:

Temperature & Energy:

  1. Give two examples of kinetic energy.
  2. Give an example of potential energy.
  3. Give an example of the conversion of either kinetic energy to potential energy or vice versa.
  4. The temperature of an object is a measure of the ___ of the molecules in the object.
    1. internal potential energy
    2. phase
    3. the random motion
    4. the collective motion
  5. A molecule that had no random motions would have a temperature of ___ Celsius.
  6. The forecast high temperature in Sydney, Australia for today is 68 F.  What is this in Celsius?
  7. The forecast low temperature in Fairbanks, Alaska for today is 2 C.  What is this in Fahrenheit?
  8. What is the process that produces the radiation that the earth receives from the sun?

Energy Transport:

  1. Give an example of the following methods of energy transport in the atmosphere:
    1. radiation
    2. convection
    3. conduction
  2. The surface temperature on Venus is 700 K. At what wavelength would the most radiant energy be emitted from the surface?
  3. If an object with a temperature of 700 K emits 30 Watts per square meter (30 W/m2), then how much energy will it emit if the temperature is increased to 770 K?

Global Energy Budget:

  1. List the ways in which the atmosphere can be heated (there are 4) starting with that which provides the most amount of energy to that which provides the smallest amount.
  2. For each of the items in the list from question 1 directly above, determine which method(s) of energy transport given in question 1 of "Energy Transport" are involved.
  3. How is the surface of the Earth heated and what does the largest part of the heating?
  4. What gases in the atmosphere absorb shortwave solar radiation?
  5. What causes the temperature to increase with altitude in the stratosphere?
  6. If in the future the albedo of the Earth/Atmosphere System remains the same, but the amount of CO2 in the atmosphere increases, what will happen to the amount of radiation absorbed by the Earth/Atmosphere System?
  7. Cloudy nights are generally warmer than clear nights because ___
    1. the clouds reflect IR radiation
    2. the clouds prevents convection just like a blanket does
    3. the clouds emit less IR radiation than the atmosphere
    4. the clouds emit more IR radiation than the atmosphere
  8. There are two surfaces with the same temperature; one is covered with ice and the other is bare soil. The amount of shortwave solar radiation measured by a satellite looking at the two surfaces would be ___.
    1. greater for the ice surface
    2. greater for the soil surface
    3. the same for both surfaces
  9. There are two surfaces with the same temperature; one is covered with ice and the other is bare soil. The amount of radiation in the longwave atmospheric window measured by a satellite looking at the two surfaces would be ___.
    1. greater for the ice surface
    2. greater for the soil surface
    3. the same for both surfaces
