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?(adsbygoogle = window.adsbygoogle || []).push({});

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! :)
