The following conversation was overheard in the corridors of a large engineering firm. New engineer: Hi, boss. Why the big smile? Old-timer: I finally won a wager with Harry Carey, from Research. He bet me that I couldnt come up with a quick but accurate estimate for the molar volume of argon at 30C and 300 bar. Nothing to it; I used the ideal-gas equation, and got about 83 cm3mol1. Harry shook his head, but paid up. What do you think about that? New engineer (consulting his thermo text): I think you must be living right. Argon at the stated conditions is not an ideal gas. Demonstrate numerically why the old-timer won his wager.
