The density of lead at 00C is 10.34 g/cm3 and x g / cm3 at 100∘C . If the coefficient of linear expansion of lead =28×10-6 /0C is, then what is the value of x

d2=d11-γ∆t=10.341-84×10-6×100=10.341-0.0084 =10.340.9916=10.25gm/cm3

$d_{2} = d_{1} [1 - γ ∆ t] = 10.34 [1 - 84 \times 10^{- 6} \times 100] = 10.34 [1 - 0.0084] = 10.34 (0.9916) = 10.25 gm / {cm}^{3}$
