A beaker made of ordinary glass contains a lead sphere of diameter 4 cm firmly attached to its bottom. At a uniform temperature of -10 degrees Celsius, the beaker is filled to the brim with 118 cm^3 of mercury, which completely covers the sphere. How much mercury overflows from the beaker if the temperature is raised to 30 degrees Celsius?
Things I know so far:
average linear expansion coefficient of glass: 9*10^-6
average linear expansion coefficient of lead: 29*10^-6
average volume expansion coefficient of mercury: 1.82*10^-4
[tex]\Delta V=\beta V_{i}\Delta T[/tex]
Wouldn't nothing spill because when the beaker's temperature rises then the beaker expands more.
If I'm wrong then could someone lead me into the right direction?
Thanks in advance! :)
