Homework Statement



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

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

Homework Equations



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

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!
