Boltzmann statistics of Ideal gas

In statistical mechanics and thermodynamics, Maxwell - Boltzmann statistics explains the statistical distribution of the energies of the classic gas molecules over different states in thermal equilibrium. Maxwell Boltzmann statistics helps us to derive the Maxwell - Boltzmann distribution of ideal gas molecules, which is the result of the kinetic theory of gases.

From the surreal realm of deep-seahydrothermal vents 200 miles offshore from Puget Sound, comesa newly discovered hyperthermophilic—or extreme heat-loving—microbe that holds the record for the hottest existence known toscience. This microbe is tentatively known as Strain 121 for thetemperature at which it thrives: 121 °C. (At sea level, water at thistemperature would boil vigorously, but the extreme pressures atthe ocean floor prevent boiling from occurring.) What is this temperature in degrees Fahrenheit?

You are using a thin layer of epoxy to bond a Silicon chip to a pure aluminum plate that acts as a heat sink (epoxy layer 0.0200mm). The Silicon chip (k = 149.0 W/(m-K) is 0.200 mm thick, and has dimensions of 25.0mm by 25.0mm. The pure aluminum plate is 0.850cm thick, and has the same dimensions as the Silicon chip. The hot side of the silicon chip is measured to be 62.0°C; the cold side of the pure aluminum plate is measured to be 31.0°C. Assuming steady-state conduction (with the thin layer of epoxy acting as contact resistance, see Table 3.2.) determine the heat transfer rate through the chip. Do not add in an addition resistance due to the thickness of the epoxy layer, this has been incorporated into the contact resistance.
In 1923, the United States Army (there was no United States Air Force at that time) set a record for in-flight refueling of airplanes. Using two refueling planes, an Airco DH-4B biplane was able to remain in flight for 39 h. During the flight, the refueling planes were able to air-transfer a total of 687 gallons of fuel to the plane in 9 refueling transfers. Assume that the refueling nozzle had a diameter of 1.55 in and each refueling took 2.35 min to perform. Calculate the velocity of the fuel through the nozzle. Assume that the fuel filled the entire cross-sectional area of the nozzle.
