Problem P. 4704. (February 2015)

P. 4704. Calculate the cubic content of the spherical bulb of a mercury in glass thermometer at a temperature of \(\displaystyle 0~{}^\circ\)C, if the cubic content of that part of the thermometer which is between the \(\displaystyle 0~{}^\circ\)C mark and the \(\displaystyle 100~{}^\circ\)C mark is 5 mm\(\displaystyle {}^3\). The coefficient of linear expansion of glass is \(\displaystyle 8\cdot 10^{-6}~(1/{}^\circ \rm C)\), and the coefficient of volume expansion of mercury is \(\displaystyle 1.8 \cdot 10^{-4}~(1/{}^\circ \rm C)\).
