Question

A closed glass bulb contains some mercury.Volumes of the empty space of the bulb at 0°c and 40°c are 1cm^3 and 0.98 cm^3 respectively. Determine the volume of mercury. Assume linear expansion of glass 7.2×10^-6°c^-1 and volume expansion of mercury 1.81×10^-6°c^-1

Answer 1

as it is thermometer I think
