A glass flask is filled up to a mark with \( 50 \mathrm{cc} \) of mercury at \( 18^{\circ} \mathrm{C} \). If the flask and contents are heated to \( 38^{\circ} \mathrm{C} \), how much mercury will be above the mark ( \( \alpha \) for glass is \( 9 \times 10^{-6} /{ }^{\circ} \mathrm{C} \) and coefficient of real expansion of mercury is \( 180 \times 10^{-6} /{ }^{\circ} \mathrm{C} \) ) \( \quad \) [EAMCET 1997; Similar MNR 1994]
(a) \( 0.85 \mathrm{cc} \)
(b) \( 0.46 \mathrm{cc} \)
(c) \( 0.153 \mathrm{cc} \)
(d) \( 0.05 \mathrm{cc} \)
