# 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 $\displaystyle 1.8 \cdot 10^{-4}~(1/{}^\circ \rm C)$.
