Fluid Substances: Hygrometry question PLEASE HELP

    Fluid Substances: Hygrometry question PLEASE HELP!!

    1. The problem statement, all variables and given/known data

    Air temperature and dew point of an enclosed area are 15*C and 8*C respectively. If the temperature falls to 10*C, what will be the change in saturated vapour pressure and the dew point?

    [Saturated vapour pressure at 7*C = 7.5 x 10^-3 mHg
    at 8*C = 8.1 x 10^-3 mHg]

    2. Relevant equations

    Relative Humidity, R = (f/F) x 100%
    where f = vapour pressure
    F = saturated vapour pressure

    3. The attempt at a solution
