Question:

A glass flask whose volume is 1000.00 cm3 at 0.0oC is completely filled with mercury at this temperature.When flask and mercury are warmed to 55.0oC, 8.95 cm3 of mercury overflow. If the coefficient of volume expansion of mercury is 18.0 X 10-5 K-1, compute the coefficient of volume expansion of the glass.
