The densities of a liquid at 0∘C0^\circ\text{C} and 100∘C100^\circ\text{C} are respectively 1.01271.0127 and 11. A specific gravity bottle is filled with 300 g300\,\text{g} of the liquid at 0∘C0^\circ\text{C} up to the brim and it is heated to 100∘C100^\circ\text{C}. Then, the mass of the liquid expelled in grams is: (Coefficient of linear expansion of glass =9×10−6 /∘C= 9 \times 10^{-6}\,/^\circ\text{C})
