Abstract
The utility model relates to an improvement on an experimental device with substance burning conditions, and provides an experimental device with substance burning conditions, which can prevent the burned white phosphorus from polluting the surrounding environment, and comprises a beaker. The essential structure is that two test tubes are arranged in the beaker, and a balloon is respectively arranged on the orifices of the test tubes.
Description
Technical field:
The utility model relates to the improvement of the experimental provision of substance combustion condition.
Background technology:
In middle school teaching, normally in the classroom, demonstrate the required condition of burning with white phosphorus; But the white cigarette severe contamination that white phosphorus burning is emitted air, influenced teachers and students' health.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of experimental provision of avoiding the substance combustion condition of white phosphorus Air surrounding environment is provided.
For achieving the above object, the utility model adopts following technical scheme, and the utility model comprises beaker, is provided with two test tubes in its structural feature beaker, is respectively arranged with balloon on the mouth of pipe of test tube.
The beneficial effects of the utility model:
Owing to be provided with two test tubes in the beaker of the present utility model, be respectively arranged with balloon on the mouth of pipe of test tube; Utilize white phosphorus to do the burning condition experiment, not only simple in structure, operation is brief, and has shortened experimental period, in addition, has avoided the pollution of white phosphorus to environment.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
The utility model comprises beaker 1, is provided with two test tubes 2,3 in the beaker 1, is respectively arranged with balloon 4,5 on the mouth of pipe of test tube 2,3.
Utilize the utility model can be the contrast experiment:
Be placed with a spot of white phosphorus in the bottom of beaker 1, pour hot water (more than 40 ℃) then in beaker 1, white phosphorus and red phosphorus are put into the bottom of test tube 2,3 respectively again, the test tube 2,3 that will have balloon 4,5 is put into hot water (more than 40 ℃).Can observe a large amount of white cigarette of white phosphorus burning generation enters in the balloon 4; And the red phosphorus in white phosphorus and the test tube 3 in the beaker 1 does not burn.Thereby illustrate that the white phosphorus burning condition must be with the oxygen contact, and temperature is more than 40 ℃.
Claims (1)
1, the experimental provision of substance combustion condition comprises beaker (1), it is characterized in that being provided with two test tubes (2,3) in the beaker (1), is respectively arranged with balloon (4,5) on the mouth of pipe of test tube (1).
