Boil water in a bowl and cool in a room. The air temperature in the room is increasing linearly according to the function Ta (t) = 22 + 0.015t (t in minutes, T in ° C). Assume that Newton's Law of Cooling is satisfied: the rate of change of water temperature is proportional to the difference between the temperature of the water and the temperature of the environment. We take the water temperature after 8 minutes and find that it...

At what temperature does the rms speed of a.) A nitrogen molecule equal the escape speed from the Earth’s surface and b.) A hydrogen molecule equal the escape speed from the Earth’s surface? c.) You will find that these temperatures are very high, so you might think that the earth’s gravity could easily contain both gases. But not all molecules move with vrms. There is a distribution of speeds, and a small percentage of molecules have speeds several times vrms....

While the majority component of air is nitrogen (N2), the gas is very unreactive because of its stability due to the triple bonds that hold the nitrogen atoms together. Nitrogen gas is, therefore, relatively unavailable for chemical reactions. One of the few ways to “fix” nitrogen, making a nitrogen compound from the elemental nitrogen in the atmosphere, is the Haber process (aka Haber - Bosch process). In this reaction, nitrogen gas combines with hydrogen gas to yield ammonia. The enthalpy...
