Test Prep Questions A constant-volume perfect gas thermometer indicates a pressure of 6.69 kPa at the triple point temperature of water (273.16K). (a) What change of pressure indicates a change of 1.00K at this temperature? (b) What pressure indicates a temperature of 100.00 C? Given that the density of air at 0.987bar and 27 C is 1.146 kg m-3, calculate the mole fraction and partial pressure of nitrogen and oxygen assuming that air consists only of these two gases. At what pressure does the mean free path of argon at 20C become comparable to the diameter of a 100 cm3 vessel that contains it? Take o =0.36nm2. A gas at 250K and 15 atm has a molar volume 12 per cent smaller than that calculated from the perfect gas law. Calculate (i) the compression factor under these conditions and (ii) the molar volume of the gas. Which are dominating in the sample, the attractive or the repulsive forces? At 300K and 20 atm, the compression factor of a gas is 0.86. Calculate (i) the volume occupied by 8.2mmol of the gas under these conditions and, (ii) an approximate value of the second virial coefficient B at 300KStep by Step Solution
