Question Number 54770 by Tawa1 last updated on 10/Feb/19
A glass bottle full of mercury has mass 500g. On being heated through  35°C,  2.43g of mercury are expelled. Calculate the mass of mercury  remaining in the bottle. (Cubic expansivity of mercury is  1.8 × 10^(−4)  K^(−1)  ,  linear expansivity of glass is  8.0 × 10^(−6) K^(−1)  .
