(a) An ideal gas initially at pressure po undergoes a free expansion until its volume is 4.10 times its initial volume. What then is the ratio of its pressure to po? (b) The gas is next slowly and adiabatically compressed back to its original volume. The pressure after compression is (4.10)1/3po. Is the gas monatomic, diatomic, or polyatomic? (c) What is the ratio of the average kinetic energy per molecule in this final state to that in the initial state?...

PRINTER VERSTON BACK NEXT Chapter 14, Problem X4 A blimp is cruising slowly at low altitude, filled as usual with helium gas. Its maximum useful payload, including crew and cargo, is 1.50E+3 kg. The volume of the helium-filled interior space is 7.76E+3 m. The density of helium gas is 0.16 kg/m, and the density of hydrogen is 0.081 kg/m. How much more payload could the blimp carry if you replaced the hellurn with hydrogen? Number Units the tolerance is +/-2%...
