Homework Help: Relating coefficients of volume, linear expansion with height

  1. Jul 15, 2007 #1
    1. The problem statement, all variables and given/known data
    a liquid with a coefficient of volume expansion B(beta symbol) just fills a spherical shell of volume Vinitial, at a temp of Tinitial. The Shell has average coefficient of linear expansion a(alpha symbol). The liquid is free to expand into a open capillary of area A projecting from the top of the sphere. A) the temp increases by delta(change symbol)T. Show that the liquid rises in the capillary by the amount delta,h given by the equation delta,h=(Vintial/A)(B-3a)(deltaT).

    -B is the beta coefficient Volume expansion(i dont know how to actually type that in)
    -a is alpha linear explansion
    -A is area

    2. Relevant equations

    3. The attempt at a solution
    im kind of confused at how to do this problem since everything is given in variables and no actual quantitys are involved, i also dont have anything in my notes in regards of how to relate changeof height to change of volume but anyhow

    my attempted solution, changeofh=(Vinitial/A)(B-3a)(Tinitial+changeofT).....
