12 Answers. if i am not mistaken, foil just turns black and starts to shrivel after some time when in contact with fire. Aluminum foil doesn't actually burn in the microwave. Since foil is a thin sheet of aluminum, aluminum does not catch fire. Relevance. This article explains why and some good alternatives . What you are seeing is called the "electro-magnetic effect." The material making up the can has a thin layer of aluminium oxide coating it which will initially prevent it from burning, so if you want to rig the question, scratch the surface of the can ("activate" it) before putting it in the flame. Why does foil not burn/catch fire when you put it in the oven? Aluminium's heat conductivity is, approximately, 4 times greater than iron's while its specific heat capacity is similar to iron. Aluminum Foil: Burn or Melt? Answer Save. The heat reflected off of the foil may also burn out the oven's heating elements. 1 decade ago. It is also rolled into wire. 1 decade ago. Because the properties of aluminium cause it to reflect and deflect heat rather than absorbing it. Either way, the can will BURN before it MELTS. Plus, if the foil is crinkled so that it forms any sharp edges, the electrical current running through the foil will cause sparks. This experiment will peer into the element Aluminum to see whether it will burn or melt when exposed to a flame. However, thin pieces of metal, like aluminum foil, are overwhelmed by these currents and heat up very quickly. 2 0. jamand . Lv 7. You may not even want to use foil on your baking pans. Favourite answer. You can run the experiment again, adding more aluminum as needed, to get alternative results. Purpose: In the world of chemistry, certain elements will behave differently when exposed to certain circumstances. So quickly in fact, that they can cause a fire. Aluminum coils [Deposit Photos] ... burn­ing mag­ne­sium par­ti­cles are placed on the sur­face of a heat­ing el­e­ment, and alu­minum par­ti­cles are placed on nee­dle points above them. Anonymous. as alu­minum is high­ly duc­tile and pli­able, it is used to make durable, light, thin foil. See what happens. Hypothesis: The hypothesis of this experiment is that Aluminum will melt when exposed to flames. If it doesn't absorb the heat then it won't overheat and catch on fire. Now light a piece of paper outside of the foil on fire placing it on or near the stash. That's why you keep aluminium foil away from a hot stove. Therefore when aluminium is exposed to a prolonged fire environment it will begin to melt (not burn), provided that the metal's temperature passes the melting point. Please conduct this experiment in a controlled environment and have water or a fire … Microwaves travel as particles called photons, and when those photons hit your aluminum, they collide with the aluminum atoms and create extra electrons.
