Question

A glass bottle of mercury was heated at the temperature rise of 35 degree celcuis,mass of mercury expelled is 2.43grams. what is its mass of mercury remaining,when it's linear expansivity is 0.00018 and it's cubic expansivity is 0.000008

Answer 1

$$Δm=m−m'\\$$

The mass of mercury left in the bottle:

$$m ' =m−Δm\\ m'=500-12.43=487.57\ g$$
