Question

A glass bottle full of mercury has mass 500 g
On being heated through 35 C, 2.43 g of
mercury are expelled. Calculaté the mass of
mercury remaining in the bottle (cubic
expansivity of mergury is 1.8 x 104 per K.
linear expansivity of glass is 8.0 x 10-6 per
K.

Answer 1

Mass is conserved. The rest is babble.
