1. A glass bottle full of Mercury has
mass' 500g, on being heated through
35°C, 2.43g of mercury are expelled
calcutate the
mass of mercury remaining in
the bottle (cubic expansivity of mercury is
1.8x10‐ per Kelvin, Linear expansivity of glass is
8. O×10-⁶ per Kelvin.)​


RĂ©pondre :

∆m = m - m'

The mass of the mercury left in the bottle

m' = m - ∆m

m' =500 - 12,43 = 487.57 g
