Say that you are in a large room at temperature tc = 300 k. someone gives you a pot of hot soup at a temperature of th = 340 k. you set the bowl up so that as it cools to room temperature the heat first flows through a carnot engine. the soup has cv= (33 j/k). assume that the volume of the soup does not change. what fraction of the total heat qh that is lost by the soup can be turned into useable work by the engine? work / qh =

Acommon technique in analysis of scientific data is normalization. the purpose of normalizing data is to eliminate irrelevant constants that can obscure the salient features of the data. the goal of this experiment is to test the hypothesis that the flux of light decreases as the square of the distance from the source. in this case, the absolute value of the voltage measured by the photometer is irrelevant; only the relative value conveys useful information. suppose that in part 2.2.2 of the experiment, students obtain a signal value of 162 mv at a distance of 4 cm and a value of 86 mv at a distance of 5.7 cm. normalize the students' data to the value obtained at 4 cm. (divide the signal value by 162.) then calculate the theoretically expected (normalized) value at 5.7 cm.
