Homework Help: Vapour pressure

  1. Feb 25, 2008 #1
    The vapor presurre of mercury is 0.00185 mmhg at 25 degree C. A single drop of Hg(0.1 mL) is spilled in a laboratory of dimensions 10m x 10m x3m. Does the entire drop evaporate? What is the partial pressure of Hg in the laboratory? (Use 13.6 g/ml for the density of Hg.) (b) The normal boiling point of mercury is 630 K. Caluculate an approimate value for vapor pressure.

    Wouldnt it eventually evaporate, reguardless of the size of the drop? Its just a matter of time due to the system being "Open" and therefore any evaporation does not go into equilibrium with the surroundings?
