Description

Melting experiment of crystal device
Technical field
The invention belongs to physical teaching model technical field, more particularly to a kind of melting experiment of crystal device.
Background technology
Fusing point is a key concept of Middle School Physics.Crystal and non-crystal foundation are to discriminate between with the presence or absence of fusing point.Thing There is the solid matter referred to as crystal of definite melting point in matter, do not have the solid matter referred to as amorphous of definite melting point in fusion process Body.And these concepts are built upon on the basis of experiment.It is difficult to set up the accurate concept of science without successfully experiment. However, in classroom teaching, teacher carries out experimental implementation according to teaching material, it is easy to failure.
It is different to the material of the experimental crystal employed in melting experiment in the teaching material of the various versions in various regions, have plenty of Using ice as the material tested, convenient material drawing, but ice is not just easy to maintain in southern area, and the process of fusing is too fast.Teach in Zhejiang The experiment material that version science is used is hypo (i.e. sodium thiosulfate), and experimental provision is using the built-in small test tube of 500ML large beakers Method, large beaker and thermometer are fixed on iron stand, are added water in large beaker, and the bottom of large beaker is heated using alcolhol burner, sea Ripple is placed in carries out heating water bath in small test tube.Existing experimental provision has a disadvantage that:
(1) Preparatory work of experiment is cumbersome, it is necessary to set up iron stand, and each experiment equipment is placed on iron stand easily to be touched down and falls It is bad.In addition, the course time of Zhejiang religion version teaching material arrangement has been at the beginning of 12 months by the end of November, Zhejiang temperature now be usually 2℃-10℃.If water temperature begins to warm up the fusing point of the hypo that reach 48 DEG C from room temperature, duration of a period is inadequate.Therefore Teacher also needs to prepare 40 DEG C of warm water.
(2) temperature is relatively low when due to being tested, the difference that warm water is easily lowered the temperature with alcolhol burner flame size, experimental period It is whard to control.
(3) when testing, the water of 300~400ML need to be heated with alcolhol burner, is also the inadequate main cause of experimental period.
(4) during student experimenting, when hypo is filled into small test tube, medicine is easily trickled down.
(5) experimental result is often undesirable., every 1 minute reading, fusion process duration is often too for requirement of experiment Short, the platform data that can be got sometimes only has to be melted in 2~3 groups, i.e., 2~3 minute and has completed.So that crystal and non-crystal Fusing difference is less obvious.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of melting experiment of crystal device, it is being reduced Hypo is more quickly heated while energy resource consumption, the purpose for shortening experimental period is reached.
To achieve these goals, technical scheme is as follows:A kind of melting experiment of crystal device, including cup, Base, thermometer, the bottom of cup are provided with the protuberance for housing hypo, and the outer surface of protuberance is provided with spacer, every Gap is formed between set and the outer surface of protuberance, spacer is provided with cup, cup is divided into liquid feeding space by spacer With dosing space, liquid feeding space connects with gap, and dosing space connects with protuberance;Cup has cup lid, and thermometer is fixed on cup Cover, the bottom of thermometer extends to protuberance;The depression for housing protuberance and spacer, the week of depression are provided with base Side sets heating wire, and heating wire is connected with plug.
This programme has abandoned the experiment model of original iron stand plus beaker, the setting of two sections formula has been carried out, by protuberance After spacer insertion depression, the stabilization fixation of package unit can be realized, cup is not easy to be knocked over by student., it is necessary to logical before experiment Liquid feeding space toward water filling in the gap of spacer and protuberance is crossed, during heating, it is only necessary to heat the water in gap, and traditional experiment is filled Putting needs for the water of 300~400ML to be heated to required temperature.On the other hand, traditional heating mode is only in the bottom of large beaker Heating, and this programme carries out comprehensive heating by the heating wire on the periphery that is recessed to protuberance.In addition the setting of cup lid, reduces Heat loss inside cup, can be heated to 50 degree or so in 5~10 minutes or so by the water of natural temperature in gap.
Cup lid another important function is:Plus thermogenetic steam is when up rushing, cup lid can be made to produce slight top up and down Winnow with a dustpan, the thermometer being fixed on cup lid can play a part of to stir hypo with slight the jolting of cup lid, be conducive to the equal of hypo It is even to be heated.
In addition, by liquid feeding space toward water filling in the gap of spacer and protuberance, facilitating water filling.By dosing space toward convex Go out in portion plus hypo, be convenient to, medicine is not easy to trickle down.
As improvement, passage is provided between the liquid feeding space and dosing space.Passage is used for the aquatic products in gap Raw hot gas is transmitted to the top of hypo.Hypo is the non-conductor of heat, and the program is conducive to the thermally equivalent of hypo.
As a further improvement, the passage is formed on spacer or is formed between spacer and cup lid.
Used as improvement, the height of the cup is 1~3 centimetre.Because water-bath is only in the protuberance positioned at bottom of cup Carry out, compared with conventional large beaker, water is not refilled in cup, so cup is shorter.
Used as improvement, the height of the protuberance is 2~4 centimetres.
As improvement, delivery port is offered on the cup, delivery port is connected with liquid feeding space.During filling water, if Water overflows from delivery port, illustrate in the gap of spacer and protuberance topped up with water.
Used as improvement, the temperature is calculated as RC-4 thermometers.RC-4 thermometer energy time recordings simultaneously store measured temperature Degree.Such as thermometer is connected on computer, measured data can directly on the computer screen by data processing software Show.
As improvement, heat transfer sheet is provided with the depression, heating wire winding is in the outer surface of heat transfer sheet.When protuberance and After spacer insertion depression, heat transfer sheet wraps surrounding and the bottom of spacer, gives hypo and uniformly heats.
As a further improvement, regulation switch is provided with the base, by adjusting switch to the electricity by heating wire Stream size is adjusted.Electric current by heating wire is bigger, then heat rapider.When just beginning to warm up, can increase by electricity The electric current of heated filament.
As improvement, heat-barrier material is filled with the base, to reduce the loss of heat.
In sum, the present invention has design advantages of simple, structure novelty, effect clear advantage.With traditional experiment Device is compared, and can reduce the consumption of the energy, and hypo can be quickly and evenly heated again, is aided with RC-4 thermometers, melts crystal Changing experiment 10 minutes or so can complete, and can obtain preferable experimental result.
