Question

If the alarm triggers (besides worrying about a mercury spill), the person in the lab will have to correctly answer a series of One of his other assistants poured 998.00 cm3 of liquid mercury into a 1000.00-cm3 -flask when both the mercury and the glass were at 4.0 ◦C. Dr. von Silliness has asked you to determine the maximum temperature he can heat the system to (to the thousandth of a degree Celsius) before the mercury overflows, if mercury has a coefficient of volume expansion of 18.0 × 10−5◦C −1 and the glass of the flask has a coefficient of volume expansion of 1.8 × 10−5◦C −1 2.

Answer: 16.373 C*

If the mercury overflows, it’ll trigger an alarm in the lab. Dr. von Silliness wants to keep the lab at exactly 16.370 ◦Cwhile the mercury alarm is in place. How long would a person of average body size (surface area of about 1.8 m2 and normal body temperature of 37◦C) have to spend in the lab which holds 2700 moles of air to trigger the mercury alarm?

Answer: 5.91*10^4 Seconds

questions about heat engines, pumps, and refrigerators, classifying them as“ideal”, “possible”, “impossible due to the first law”, and “impossible due to the second law”. Dr. von Silliness has asked you to create (and classify) one of each kind operating between a hot reservoir at 600 K and a cold reservoir at 16.370◦C. Each one should produce 1000 J of useful work.
