Abstract
The invention provides an experimental device for combustion of a thin iron wire in oxygen. The experimental device is mainly characterized by being composed of a wide mouth bottle (1) equipped with manganese dioxide (13), a rubber plug (2), a separating funnel (3) equipped with a hydrogen peroxide solution, a first gas-guide tube (4), an emulsion tube (5), a second gas-guide tube (6), a thermal insulation board (7) with a circular hole in the middle, an alcohol burner (8), a toughened glass cylinder (9) with a circular hole in the wall and openings at the two ends, an iron support (10) with an iron clamp (11), and the thin iron wire (12). The experimental device can be used to overcome defects, of experimental devices in teaching materials, that an experimenter has a trouble in preparing a bottle of oxygen in advance, the thin iron wire is not likely to combustion due to the fact that combustion of a matchstick consumes part of the oxygen and the oxygen concentration in the gas bottle is decreased, and the thin iron wire is not likely to combustion due to the temperature is not high enough when the matchstick is used for ignition; and the experimental device of the invention is simple in operation, obvious in phenomena and high in success rate.

Page【Activity with probe into】The experiment that middle thin wire burns in oxygen is so demonstration：Fasten matchstick in spiral helicine thin wire end, be clipped in thin wire with crucible tongs and light the matchstick of end, whne matchstick will after-flame when, by their upper rights, lower slow stretching into is filled with the gas bottle of oxygen.Add a small amount of water at gas bottle bottom in advance（Or spread a small amount of sand）, prevent the solid matter of reaction generation from splashing down bottom of bottle, cause gas bottle to burst.Do so experiment existing defects in teaching material：
1
, to prepare the oxygen of a gas bottle in advance, trouble wastes many times.
2
, because matchstick burning will consume part of oxygen, cause the oxygen concentration in gas bottle to decline, thus thin wire can not usually burn, and make the failure of an experiment.
3
, ignited with matchstick, temperature is not high enough, and thin wire can not burn.
