Abstract
The utility model relates to a liquid boiling point and air pressure relation demonstrator which comprises an iron support, a spirit lamp, a flask, a thermometer, a rubber plug, a gripper, a conduit and a connecting pipe. The flask is filled with liquid. The rubber plug is installed at an upper opening of the flask. The thermometer and the conduit penetrate through the rubber plug and then are installed in the flask; wherein, the bottom of the thermometer is immerged into the fluid, and the rubber plug is plugged tightly on the flask for sealing; the flask is spanned on the iron support, and the spirit lamp is arranged under the flask to form a liquid boiling point heater. Two liquid boiling point heaters are arranged oppositely. Two ends of the connecting pipe are respectively connected with output pipes of two liquid boiling point heaters, the connecting pipe is equipped with the gripper, to form the liquid boiling point and air pressure relation demonstrator. The liquid boiling point and air pressure relation demonstrator has the advantages of intuitive performance and strong contrastive property for experimenting, simple and easily obtained equipment and good effect.
Description
Technical field
The utility model relates to physical teaching aid, particularly relates to boiling point of liquid and air pressure relation demonstration device.
Background technology
The boiling point of liquid raises with the increase of air pressure, and with the reducing and reduce of air pressure, in existing physics teaching equipment, the teacher generally can only use common conical flask to do experiment, and operational danger is big, and is dangerous, and the time is short, DeGrain.
Summary of the invention
The technical problems to be solved in the utility model, it is directly perceived to provide a kind of experiment, and comparative is strong, safety, effective boiling point of liquid and air pressure relation demonstration device.
The technical scheme that adopts is:
Boiling point of liquid and air pressure relation demonstration device comprise iron stand, spirit lamp, flask, thermometer, rubber stopper, clip, conduit and connecting pipe.Dress liquid in the described flask, rubber stopper is contained in flask place suitable for reading, thermometer and conduit all pass rubber stopper and pack in the flask, wherein the thermometer bottom is immersed in the liquid, with the also sealing on flask of rubber stopper jam-pack, flask support is located on the iron stand, spirit lamp is placed on the flask below, constitute the boiling point of liquid well heater, adopt described two boiling point of liquid well heaters staggered relatively, the connecting pipe two ends connect two efferent ducts on the boiling point of liquid well heater respectively, on its connecting pipe clip are housed, and constitute boiling point of liquid and air pressure relation demonstration device.
The utlity model has when experiment intuitive, comparative is strong, equipment is simple and easy to, effective advantage.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
