A mercury thermometer has a capillary tube of $$0.25\mathrm{mm}$$ diameter. The bulb and capillary tube are made of zero expansion material. Assume the operating temperature is $$20^{?}\mathrm{C}$$ and the coefficient of volumetric expansion of mercury is 0.181 $$\times 10^{?3}{/}^{?}\mathrm{C}$$ What is the thermometer bulb volume if a sensitivity of $$2.5\mathrm{mm}/{}^{?}\mathrm{C}$$ is desired?
