Abstract
The utility model relates to device for liquid vaporization and gas liquefaction, and belongs to a teaching demonstration device. The utility model provides a device for liquid vaporization and gas liquefaction, and can be used for the demonstration in the class. The utility model comprises a glass bottle, the structural main point is that a conduct pipe having a valve is arranged in a cork of the bottle mouth, and the side of the glass bottle is provided with a valve; as well as the glass bottle is filled with red liquid alcohol.
Description
Technical field:
The utility model is to belong to teaching demonstration device.
Background technology:
Existing vaporizing liquid, gas liquefaction still do not have the apparatus for demonstrating on the classroom, so the student feels abstract when learning, and have increased scholastic difficulties.
The utility model content:
The utility model is exactly at the problems referred to above, provides a kind of for a kind of vaporizing liquid of demonstrating on the classroom, the device of gas liquefaction.
The utility model adopts following technical scheme: the utility model comprises vial, and its structural feature is to be provided with the conduit with valve in the cork of bottleneck, and the side of vial has valve; The liquid red alcohol of containing in the vial.
The beneficial effects of the utility model:
1, good demonstration effect:
See through vaporization, the liquefaction process of liquid red alcohol in the vial, students can obviously be found out variation wherein, and the demonstration effect is fine;
2, simple in structure:
Main member of the present utility model is vial, conduit, and is simple in structure, and processing ease.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model comprises vial 2, is provided with the conduit 6 with valve 5 in the cork 4 of bottleneck, and the side of vial 2 has valve 3; The liquid red alcohol of containing in the vial 21.
Below in conjunction with a description of drawings course of action of the present utility model:
Put into vial 2 a small amount of red alcohol 1, then, clog 2 mouthfuls of vials with cork 4 with conduit 6.
Again above-mentioned vial 2 of the present utility model is placed cold water, can see vial 2 interior liquid red alcohol 1 this moment and increase, simultaneously, red gas reduces; Here it is finishes the process that a gas becomes liquid.
