Homework Help: Thermal Dynamics

  1. Jul 16, 2007 #1
    1. The problem statement, all variables and given/known data

    A glass flask whose volume is [tex]1000cm^{3}[/tex] at a temperature of [tex]0.00*10^0[/tex] Celsius is completely filled with mercury at the same temperature. When the flask and mercury are warmed together to a temperature of 52 Celsius, a volume of [tex]8.35cm^{3}[/tex] of mercury overflows the flask.

    the coefficient of volume expansion of mercury is [tex]\beta_{Hg} = 1.80*10^{-4}[/tex]K

    Calculate the change in volume of the mercury [tex]\Delta V_{Hg}[/tex] during heating.

    2. Relevant equations

    [tex]\Delta T = T_f - T_i[/tex]
    [tex]\Delta V = \beta V_o \Delta T[/tex]

    3. The attempt at a solution

    [tex]\Delta T = 325.15K - 273.15K[/tex]
    [tex]\Delta T = 52K[/tex]

    [tex]\Delta V_{Hg} = (1.80*10^{-4})(1000)(52)[/tex]
    [tex]\Delta V_{Hg} = 7.8 cm^3[/tex]

    I think I am doing this right but the program keeps saying it's wrong.

    Any ideas?

    Never mind, I calculated the last equation wrong.

    Thanks anyways!
