Question

Equal masses of aluminium and iron, each in cylinders of equal height with insulated sides, are heated to 60°C and placed on large ice blocks at 0°C. Given s A l ​ = 0.22 , ρ A l ​ = 2.7 g / cm 3 ; s F e ​ = 0.11 , ρ F e ​ = 7.8 g / cm 3 , the ratio of penetration depths (Al : Fe) is:

x ∝ A m s ​ and equal mass and height give A ∝ ρ 1 ​ , so x ∝ s ρ . Ratio = 0.11 ( 7.8 ) 0.22 ( 2.7 ) ​ = 0.858 0.594 ​ = 0.6923 = 13 9 ​ . A. \end{document}
