Homework on pressure

  1. Mar 5, 2008 #1
    I already know that one atmosphere equals to 760 mm-Hg. But, I don't get the following question:
    Q. What is the height of a column of mercury supported by one atmosphere of pressure?
    Although this is homework question, I want an quick answer, I already know that 1 atm = 760 mm-Hg, but what is "height of a column" definition?

    What do you think "mm-Hg" means?

    I think it means millimeters per mercury. So, is the answer 760 mm-Hg correct?

    It means millimeters of mercury.
    Assuming the top of the mercury column is closed (and empty), the answer would be 760 mm.
