# A glass flask of volume one liter is filled completely with mercury at $0^{\circ}C$. Then flask is now heated to $100 ^{\circ} C.$ Coefficient of volume expansion of mercury is $1.82 \times 10^{-4} /^{\circ} C$ and coefficient of linear expansion of glass is $0.1 \times 10^{-4}/^{\circ} C$. During this process, amount of mercury which overflows is

$(a)\;21.2\;cc \quad (b)\;15.2\;cc \quad (c)\;2.12\;cc \quad (d)\;18.2\;cc$

(b) 15.2 cc
