Under what circumstances would you expect a gas to behave significantly differently than predicted by the ideal gas law?
An ideal gas expands quasi-statically and isothermally from a state with pressure p and volume V to a state with volume 4V. Show that the work done by the gas in the expansion is pV(ln 4).
Unreasonable results. (a) Find the temperature of 0.360 kg of water, modeled as an ideal gas, at a pressure of 1.01105 Pa if it has a volume of 0.615 m3. (b) What is unreasonable about this answer? How could you get a better answer?
The excess internal energy of metabolism is exhausted through a variety of channels, such as through radiation and evaporation of perspiration. Consider another pathway for energy loss: moisture in exhaled breath. Suppose you breathe out 22.0 breaths per minute, each with a volume of 0.600 L. Suppose also that you inhale dry air and exhale air at 37C containing water vapor with a vapor pressure of 3.20 kPa. The vapor comes from the evaporation of liquid water in your body. Model the water vapor as an ideal gas. Assume its latent heat of evaporation at 37C is the same as its heat of vaporization at 100.C. Calculate the rate at which you lose energy by exhaling humid air.
An aluminum rod 0.500 m in length and with a cross sectional area of 2.50 cm2 is inserted into a thermally insulated vessel containing liquid helium at 4.20 K. The rod is initially at 3(H) K. (a) If one-halt of the rod is inserted into the helium, how many liters of helium boil off by the time the inserted half cools to 4.20 K? Assume the upper half does not yet cool, (b) If the circular surface of the upper end of the rod is maintained at 300 K. what is the approximate boil-off rate of liquid helium in liters per second after the lower half has reached 4.20 K? (Aluminum has thermal conductivity of 3 100 YV/m K at 4.20 K; ignore its temperature variation. The density of liquid helium is 125 kg/m3.)
(II) If 16.00 mol of helium gas is at 10.0°C and a gaugepressure of 0.350 atm, calculate (a) the volume of thehelium gas under these conditions, and (b) the temperatureif the gas is compressed to precisely half the volume at agauge pressure of 1.00 atm

How much steam at 250°F would be required to heat 10 lb of water from 70°F to 210°F in a direct steam injection heater? The answer must be 1.42 lbs
Suppose a tank contains 666 m3 of neon (Ne) at an absolute pressure of 1.01x105 Pa. The temperature is changed from 293.2 to 294.9 K. What is the increase in the internal energy of the neon?
(II) You buy an “airtight” bag of potato chips packaged atsea level, and take the chips on an airplane flight. Whenyou take the potato chips out of your “carry-on”bag, you noticeit has noticeably “puffed up.” Airplane cabins are typicallypressurized at 0.75 atm, and assuming the temperatureinside an airplane is about the same as inside a potato chipprocessing plant, by what percentage has the bag “puffedup” in comparison to when it was packaged?
