Question: 4 A sheet of copper is exposed to oxygen at 1000°C. Afier 100 h. 0.245 g of copper are lost per em of surface area; after 250 h, 0.385 g/ cm² are lost; and after 500 h, 0.560 g' em are lost. i. Determine whether oxidation is parabolic, linear, or logarithmic ii. Calculate the time required for a 0.76-cm sheet of copper to be completely oxidized. The sheet of copper is oxidized from both sides.
