Please fill in all the right and complete the correct answers to these 18 questions that I attach. There is a 2 document that I’ve attach that might help fill in the questions.

QUESTION 1

  1. Using the data that you collected, graph how the energy emitted by the light bulb (in W/m2) changes with temperature (°C). Display temperature on the x-axis (horizontal) and the energy emitted by the light bulb on the y-axis (vertical). Once you have drawn a graph, digitally capture the graph on the screen and submit it through this link.

QUESTION 2

  1. The light bulb emits visible radiation when the dimmer is set to zero.
  2. True
  3. False

QUESTION 3

  1. According to the observations, as the temperature of the light bulb increases, the perceived brightness of the bulb _____.
  2. A.decreases
  3. B.remains constant
  4. C.increases and then decreases
  5. D.increases

QUESTION 4

  1. According to the observations, as the temperature of the light bulb increases, the amount of emitted radiant energy _____.
  2. A.increases
  3. B.increasing and then decreases
  4. C.decreases
  5. D.remains constant

QUESTION 5

  1. The color of the light bulb changed as the temperature of the light bulb changed.
  2. True
  3. False

QUESTION 6

  1. What do the observations (your graph) tell you about the relationship between temperature and energy emission by the light bulb? Select two from the list of choices.
  2. A.Linear
  3. B.Non-linear

QUESTION 7

  1. A surface that receives a greater amount of insolation is generally warmer than a surface that receives a smaller amount of insolation if all other conditions are identical.
  2. True
  3. False

QUESTION 8

  1. On the surface level, a location with a large sky view (such as the rose garden on Chico State campus) receives a greater amount of daily insolation than a location surrounded by vegetation and buildings (such as the area near Butte Hall and along Big Chico Creek) does.
  2. True
  3. False

QUESTION 9

  1. If 100 units of incoming solar radiation arrive on an asphalt surface with an albedo value of 0.15, how many units of incoming solar radiation are reflected? Enter a numerical value.

QUESTION 10

  1. If Chico receives 950 W/m2 of incoming solar radiation, how much of it is reflected by a grass surface with an albedo value of 0.25? Enter a numerical value with one decimal place.

QUESTION 11

  1. Warming temperatures melt snow and ice in the Arctic region which will expose darker soil. In this case, the albedo of this surface will _____.
  2. A.decrease
  3. B.decrease and then increase
  4. C.increase
  5. D.remain the same
  6. E.increase and then decrease

QUESTION 12

  1. How much insolation does the Earth’s surface receive at night?
  2. A.90% of the daytime value
  3. B.50% of the daytime value
  4. C.10% of the daytime value
  5. D.0% of the daytime value
  6. E.-10% of the daytime value

QUESTION 13

  1. A warmer body emits more energy than a cooler body does if all other factors are the same. Even during the summer time, the sky is very cold (see the table in the Lab Document), while the ground surface gets really hot. Which one of the followings emits more energy?
  2. A.Ground surface
  3. B.Sky

QUESTION 14

  1. The average Earth’s surface temperature is 288 K. The wavelength of peak emission of radiation from the Earth’s surface is _____ µm.

QUESTION 15

  1. If the temperature of an object is 1811 K (melting point of iron), the wavelength of peak emission of radiation from this object is _____ µm. Enter a numerical value with two decimal places.

QUESTION 16

  1. If the temperature of an object is 8000 K, the wavelength of peak emission of radiation from this object is 0.3623 µm. What part of electromagnetic spectrum does this wavelength of peak emission fall?
  2. A.Near infrared
  3. B.Thermal infrared
  4. C.Visible light
  5. D.Ultraviolet

QUESTION 17

  1. The surfaces that you measured in this lab were emitting visible light.
  2. True
  3. False

QUESTION 18

  1. If the surface that you measured in this lab were NOT emitting visible light, why?
  2. A.Because the temperature was too low
  3. B.Because there was no direct beam of insolation
  4. C.Because it was daytime
  5. D.Because the albedo value was zero
