Question:
A sheet of copper is exposed to oxygen at 1000°C. After 100 h, 0.246 g of copper are lost per cm2 of surface area; after 250 h, 0.388 g/cm2 are lost; and after 500 h, 0.550 g/cm2 are lost. Determine whether the oxidation is parabolic, linear, or logarithmic, then determine the time required for a 0.75-cm sheet of copper to be completely oxidized. The sheet of copper is oxidized from both sides.
