# Question: A Pyrex beaker that has a capacity of 1000 cm3

A Pyrex beaker that has a capacity of 1000 cm3 at 20 °C contains 990 cm3 of mercury at that temperature. Is there some temperature at which the mercury will completely fill the beaker? Justify your answer. (Assume that no mass is lost by vaporization and include the expansion of the beaker.)
