Answer:
Let volume of mercury at 20°C and 100°C are Vm100 and Vm20 respectively.
we have Vm100= Vm20(1+γmΔT) = 256(1+1.8×10-4 ×80) cm3....................(1)
γm is volume expansion coefficient of mercury. ΔT is increase of temperature
Let volume of glass at 20°C and 100°C are Vg100 and Vg20 respectively.
we have Vg100= Vg20(1+3×αg×ΔT) = 256(1+3×4×10-6 ×80) cm3....................(2)
αg is linear expansion coefficient of glass. Volume expansion coefficient is 3 times of linear expansion coefficient
excess volume of mercury that overflow is obtained by subtracting (2) from (1).
excess volume of mercury = 3.44 cm3
