The experiments demonstrated by the molecule property demonstrator have distinct phenomena and strong contrast, and can emphasize the change processes of the experiments.
Description
Technical field
The utility model relates to a kind of experimental apparatus, especially relates to the instrument for molecular property demonstration.
Background technology
On classroom, junior middle school, traditional while doing molecular motion lecture experiment, add respectively 100ml water and 100ml alcohol with 200ml graduated cylinder, the phenomenon of its volume-diminished 4ml illustrates the intermolecular interval that has, because water and alcohol in 200ml graduated cylinder form by mixing forebody-afterbody product moment the about 5mm of difference in height that liquid level declines, difference in height is smaller, is difficult to allow the full classmate of class all see clearly on dais.
Summary of the invention
The purpose of this utility model is for make molecular motion lecture experiment of graduated cylinder, and the smaller problem of difference in height that the liquid level forming before and after water and alcohol mix declines, provides demonstration device of molecular property.
For achieving the above object, the utility model is by the following technical solutions:
Demonstration device of molecular property, comprise bottle I, bottle II and the bottle III of three given volumes, between bottle I and bottle II, be connected with bottleneck, bottleneck is provided with scale mark I, between bottle II and bottle III, be provided with display tube, on display tube, be provided with calibrated dial line, the scale value of calibrated dial line is 0.1ml, the bottle stopper that bottle III is topmost provided with bottleneck and matches with bottleneck.
Bottle I, bottle II and bottle III volume are 150ml, and display tube scope is 7.7ml～10ml, and display tube height is 200mm.
Bottle I, bottle II and bottle III volume are 100ml, and display tube scope is 5.0ml～6.6ml, and display tube height is 150mm.
The utlity model has following advantage: the utility model is simple in structure, easy to operate, practical, the utility model both can do the miscible volume-diminished experiment of two kinds of liquid, also can do miscible volume and increase experiment; Both can do the qualitative experiment of volume change, also can quantitatively calculate volume change value; Can do continuously fluid molecule diffusion experiment, the miscible volume change experiment of liquid and the experiment of expanding with heat and contract with cold; Can do gas molecule diffusion experiment.The lecture experiment that the utility model carries out, phenomenon distinctness, contrast property is strong, the change procedure that energy excrescence reality is tested.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1, bottle I, 2, bottle II, 3, bottle III, 4, scale mark I, 5, display tube, 6, bottleneck, 7, bottle stopper, 8, scale mark II.
Embodiment
As shown in Figure 1, demonstration device of molecular property, comprise bottle I 1, bottle II 2 and the bottle III 3 of three given volumes, between bottle I 1 and bottle II 2, be connected with bottleneck, bottleneck is provided with scale mark I 4, between bottle II 2 and bottle III 3, is provided with display tube 5, is provided with calibrated dial line on display tube 5, the scale value of calibrated dial line is 0.1ml, the bottle stopper 7 that bottle III 3 is topmost provided with bottleneck 6 and matches with bottleneck.
The utility model principle: (V
1+ V
2) × K < π d
210h/4
Wherein: K=2.3, V
1for the volume of bottle I, V
2for the volume of bottle II, the diameter that d is display tube, the height that h is display tube, the unit of V is ml, and the unit of d is mm, the mm of unit of h.
Embodiment 1: when test, bottle I, bottle II and bottle III volume are 150ml, display tube scope is 9.0ml, display tube height is 200mm, remove bottle stopper 7, first pour the alcohol that is mixed with red ink into scale mark I 4 places, then add water to rapidly scale mark II 8 places, there are two phenomenons: the first phenomenon is that the alcohol shape that is mixed with red ink is risen and constantly diffusion slowly as " smoke, mists and clouds continuously " simultaneously, the color of upper part is more and more denseer, lower part color is more and more lighter, and 2min upper back color approaches bottom color; The second phenomenon is that the liquid level at scale mark II 8 places declines with speed faster, 2min decline 70.0mm.The first phenomenon has illustrated the diffusion phenomena of molecule, and the second phenomenon explanation alcohol and water mixed volume dwindle, and intermolecular have an interval.Add again alcohol if first add water, on upper strata, only have a small amount of diffusion two kinds of liquid contact positions because alcohol density is less than the density of water, need turned upside down vibration to mix 2 times, the liquid level 155.0mm that can decline.Do the experiment of expanding with heat and contract with cold of alcohol and the miscible rear solution of water with this instrument: first this instrument is immersed in the hot water of 90 DEG C of left and right, liquid level rises rapidly, 1min rising 100.0mm, take out instrument, then it is immersed in cold water, liquid level declines rapidly again, because the expansion coefficient of alcohol water blend is larger, so expand with heat and contract with cold, phenomenon is obvious, and owing to being mixed with red ink colour developing in its mixed liquor, the Phenomena Observation of liquid surface lifting process must be perfectly clear again.
Embodiment 2: when test, bottle I, bottle II and bottle III volume are 100ml, display tube scope is 6.0ml, display tube height is 150mm, remove bottle stopper 7, first pour the alcohol that is mixed with red ink into scale mark I 4 places, then add water to rapidly scale mark II 8 places, there are two phenomenons: the first phenomenon is that the alcohol shape that is mixed with red ink is risen and constantly diffusion slowly as " smoke, mists and clouds continuously " simultaneously, the color of upper part is more and more denseer, lower part color is more and more lighter, and 2min upper back color approaches bottom color; The second phenomenon is that the liquid level at scale mark II 8 places declines with speed faster, 2min decline 115.0mm, the first phenomenon has illustrated the diffusion phenomena of molecule, the second phenomenon explanation alcohol and water mixed volume dwindle, intermolecular have an interval, being perfectly clear of the Phenomena Observation of liquid surface lifting process.
