Physics-7A Lecture A Quiz 1 Problem 1 Rubric Part (a) 30% Q (10): Correct answer (see solution). W (9.5): Small arithmetic error. The two most common examples were reading the labels on the graph incorrectly, and making an error while subtracting. Students that got a W demonstrated that they knew how to do the problem, and made no mistakes besides an arithmetic error. E (7.7): Conceptual error in finding E A . The most common example was to confuse the values of E on the x-axis with the change in energy during a process. A student might think that E A = 250 J instead of 1500J because that is the value of E A at the intermediate point. The differences between start and finish are what matter, not the actual values. R (7): Shows understanding that heat must flow from B to A, but does not find a numerical estimate for any E's or temperatures. T (5): There is some attempt to answer the question; however, there are serious conceptual flaws and it is not clear that the student understands the physics of the problem. Y (0): Blank or effectively blank. Part (b) 30% Q (10): Correct answer (see solution). W (8.5): Answers correctly that A will not boil. However, the justification is missing, incorrect, or is just based on intuition. One example is that the student assumes that thermal equilibrium means that A and B will reach the same energy instead of the same temperature. Another example is a statement that
