Texts: Get the right answer (order of magnitude, when applicable). Some answers depend on your assumptions, which must be reasonable; you cannot assume a human’s breath to be 100 L, for example; Demonstrate to me and the TAs that you actually understand the problem; Explain how you navigate it. Don't just show your work, show your thought process. Include words to explain what you did, and why. We don't expect essays, but a sentence or two goes a long way.
Question 4:
Venus's mean surface temperature is actually hotter than Mercury's mid-afternoon temperature, despite being nearly twice as far from the Sun. The difference arises because Venus has many more layers in its atmosphere than Mercury. These extra layers actually contribute to the ability for the atmosphere to trap heat.
In lesson 5, we talk about a perfect single-layer atmosphere and get two energy balance equations that we use to find the surface temperature of Earth. What would be the temperature of Earth if we added an extra perfect (i.e., with emissivity equal to 1) layer, so we had two in total? With two layers, there are now three energy balance equations. Find them and solve for Earth's temperature.
Does your temperature agree with the 2-glass layer Greenhouse PhET?
Challenge question: Find out how many layers Earth would need to have the same surface temperature as Mercury. This is not trivial and should only be attempted for your own curiosity.
