Thermal Expansion Problem

  1. Dec 3, 2011 #1
    1. The problem statement, all variables and given/known data

    A 1-liter aluminum container at 20oC is filled with 0.975 liters of mercury at
    20oC. If both the container and the mercury are heated, at what final temperature
    will the mercury completely fill the container?
    αAl = 24 × 10-6 (Cº)-1; βHg = 1.82×10-4 (°C)-1

    Any help on this would be great. Im not sure how to get the final temperature here. I calculated the final temp for Hg only for 1L. Not sure how to include the AL container into the problem. Am I supposed to combine the formulas somehow?

    V= V + 3α V Δ T Used for AL container..not sure how to use here

    V= V + β V Δ T Used for Hg to figure final temp need to expand to 1 liter.

    thanks for the help
