SHOW LAB WORK QUESTION 9 OF 15.> In the enrichment of uranium for nuclear reactors, a gas called uranium hexafluoride (UF6) is generated and then placed in large gas centrifuges to separate different isotopes of uranium. Suppose you were to perform the same experiment with uranium hexafluoride.Given that uranium hexafluoride is much heavier than either of the gasses used in this experiment, how would you expect the value of absolute zero measured from the experiment to compare to the one...
