Imagine you are comparing the ability of electric hot plates of different sizes and temperatures to fully cook two identical large pots of spaghetti. Note that all the pots are as large as the largest hot plate. The shading of each hot plate is used to illustrate its temperature. The darker the shade, the cooler the temperature of each hot plate. For the scenario in panel A only, which hot plate (left or right) will cook the pot of pasta more quickly? If there is no way to tell, choose that option. |

Imagine you are comparing the ability of electric hot plates of different sizes and temperatures to fully cook two identical large pots of spaghetti. Note that all the pots are as large as the largest hot plate. The shading of each hot plate is used to illustrate its temperature. The darker the shade, the cooler the temperature of each hot plate. Two students are discussing the hot plates: Student 1: In panel D, the hot plate on the left cooks the pasta quicker than the one on the right even though it is smaller. The hot plate's higher temperature is what makes the pasta cook quicker. Student 2: But the size of the hot plate also plays a part in how fast the pasta cooks. If the hot plate on the left were the size of a penny, the pasta would take a really long time to cook. I bet that if the size difference were great enough, the one at the lower temperature would cook the past first. Which student has the most accurate answer? |
Student 2 |

The graph below plots the luminosity of a star on the vertical axis versus the star's surface temperature on the horizontal axis. This is called an H-R diagram. Stars U and V have the same temperature. Given that star U is much more luminous that star V, what can you conclude about the size of star U compare to V? |
Star U is larger than star V. |

The graph below plots the luminosity of a star on the vertical axis versus the star's surface temperature on the horizontal axis. This is called an H-R diagram. Star U is hotter than star X. They have the same luminosity. What can you conclude about the size? |
Star U is smaller than star X |
