A glass flask whose volume is 1000cm^3 at a temperature of 0.400^ C is completely filled with mercury at the same temperature. When the flask and mercury are warmed together to a temperature of 52.0 C, a volume of 8.25cm^3 of mercury overflows the flask. Part A If the coefficient of volume expansion of mercury is beta_Hg = 1.80×10?4/K , compute beta_glass, the coefficient of volume expansion of the glass.
