    A mercury thermometer consists of a glass bulb completely full of mercury. This is connected to an empty vertical glass tube of radius 0.01 cm. If the volume expansivity of mercury is 1.81 10−4 K−1, and the top of the mercury rises 2.3 cm for a 10◦C change in temperature, calculate the volume of the glass bulb. [Assume the expansivity of the glass is negligible when compared with that of the mercury.] Answer: 0.399 cm^3
