Modeling Laboratory Heating and Cooling An Earth heating-cooling model is useful, but it contains a lot of fac- tors that are not present on the moon. Scientists often deal with this kind of problem by doing laboratory experiments meant to simulate the conditions that they wish to study. Let's examine a simple labora- tory heating-cooling model to see if it helps us gain some insights into the moon. Figure 3 shows the experiment setup. Cup A contains ice water, while cup B contains hot water from a coffee maker. The long, thin device is a temperature probe. The experimenter heated and cooled the probe by switching it back and forth between the cups. The data col- lected represents the way in which the probe's steel body heats up and cools down. After collecting the data, the experimenter graphed it, giv- ing a simple model of heating and cooling (Figure 4). 7. Describe the shape of the curve as the probe's temperature rises (heating). Is it what you would have expected?
