Demoworks/ page 23 Metal Oxidation (Weight Gain in Metals) Objective: To observe the effects of oxidation in metals. Keywords: kinetics, oxidation Materials: • A piece of stainless steel 0.1x 5 x 5 mm • A piece of mild steel 0.1x 5 x 5 mm • Bunsen burner • A scale with milligram resolution Procedure: Clean and degrease the pieces of metal. Weigh them both and record. Heat them for approximately one minute in air (until bright red). Cool them and record the weight. The mild steel

hammer. The rubber hose is now glassy and shatters like conventional glass. Pass the shatter hose around and notice the fracture pattern is similar to a brittle material. Allow the hose the warm up to room temperature and show how the properties have recovered. Variation 1: The rubber hose can be replaced with flowers. They too shatter like glass when cooled. The fracture patterns are compelling because they resemble glass but as they warm up are delicate once again. Variation 2: Place a <span class="highlight">steel</span> rod
