Lab 11 1. Why does ice form on the aluminum cylinder in the second experiment? Does this change our results? 2. In this lab we never directly measured the temperature of the aluminum cylinder. How did we complete this lab despite this? 3. What physical quantity does the slope represent of the straight parts on the “Mass vs. Time” graph? Would this be slope be steeper, shallower, or unchanged if we used a wider mouthed cup? 4. The disabled Fukushima nuclear reactor uses plutonium fuel rods for fuel. 1 kg of plutonium produces about 500 Joules of energy every second in the form of radiation. If 1

Unformatted text preview: kg of plutonium were placed in a 200 liter tank of water initially at 20 ºC, and all the radiation is absorbed by the water, how long would it take for the water to reach its boiling point (the boiling point of water is 100 ºC)? Hint: The amount of energy the water absorbs is: t E ∆ ∆ / = 500 J/s 5. Copper has a mass density of 8.96 g/cm 3 and a specific heat of 0.386 J/(K*g). If we used a copper cylinder the same size as our aluminum one in our experiment, what do you expect would have changed?...
