Abstract
The invention discloses an experiment tool set for studying solidification and liquefaction phenomena, which comprises a cup body, and also comprises a cup lid matched with the cup body, and a temperature sensor matched with the cup lid, wherein the cup body comprises an outer cup body and an inner cup body; the cup lid comprises a lid top and a first through hole formed on the lid top; and the first through hole corresponds to the opening of the inner cup body. The experiment tool set can present the solidification and liquefaction phenomena, and reduces the influence of external environment and the tool on a tested object in the solidification and liquefaction processes to the minimum so as to truly reflect the physical change processes as much as possible.
Description
Technical field
The present invention relates to a kind of experimental tool external member, particularly relate to a kind of experimental tool external member that can present important liquefaction and curing phenomenon.This phenomenon can not present on existing experiment equipment.
Background technology
Conventionally, in the teaching of school, need to explain liquefaction and curing phenomenon and physical cause behind, change procedure etc. to student, for the mode that helps student to understand and often to strengthen remembering by experiment realizes this object.
But very inconvenient for the suite of tools of this class experiment at present, some important liquefaction and curing phenomenon can not be presented, have no way of providing the significant data of required experimentation, cannot allow student understand liquefaction and curing phenomenon physical change process behind.
The research solidification process of take is example, and as shown in Figure 1, the experimental tool external member of using at present comprises the first uncovered bottle 2, is placed in the second uncovered bottle 3 and temperature sensor 4 within the first uncovered bottle 2.In order to study curing phenomenon, between the uncovered bottle 3 of described the first uncovered bottle 2 and second, be filled with the salt solution containing ice cube, in the second uncovered bottle 3, fill the water of studied use, in water, be also provided with described temperature sensor 4, this temperature sensor 4 sends the variations in temperature data of water to outside data record and treatment facility (not shown) by wire.
Obviously, the experimental tool external member of using at present has following shortcoming:
1. the temperature of the ice cube taking out from refrigerator is approximately-15 ℃, after but ice cube is placed into salt solution, the temperature of salt solution can only reach-5 ℃ (will not near-15 ℃) conventionally, and when such environment temperature is difficult to allow the temperature of tested water solidify phenomenon to study, desired speed declines.
2. the hot-air in the external world can affect tested water temperature by unlimited bottleneck, makes the tested water can not be enough cold.
The hot-air in the external world can be by the impact of unlimited bottleneck and body the water temperature containing the salt solution of ice cube, make the salt solution can not be enough cold.
4. because described the second uncovered bottle 3 is with glass manufacture, and glass is hot non-conductor, and therefore the salt solution with ice cube will further be reduced the impact of tested water temperature.
5. most of temperature sensors 4 of selling on market are all made of metal, but because metal is hot good conductor, the metal temperature sensor 4 of the part that surfaces also can absorb a large amount of heats from air, and this heat is transmitted in tested water, thereby further reduced the fall off rate of tested water temperature.
Because the cooldown rate of tested water is less than the speed in expectation, therefore the time of experiment can continue more of a specified duration, cause the heat that obtains from environment also more, the adverse effect of bringing is thus just more significantly (above-mentioned shortcoming 2,3 and 5) also.So the temperature variation curve recording in experimentation (seeing Fig. 3) often with theoretic temperature variation curve differ greatly (seeing Fig. 2), even fundamental difference.Specifically, under the ideal state of Fig. 2, the slope at curve two ends declines rapidly, in the middle of curve, has the straight line of one section of level to maintain 0 ℃; And in Fig. 3, temperature variation curve be difficult to arrive subzero, and the temperature that also cannot observe mixture of ice and water in solidification process maintains the physical phenomenon of zero degree all the time.
The research liquefaction process of take is again example, as shown in Figure 4, in the first uncovered bottle 2, be placed with the second uncovered bottle 3, in the second uncovered bottle 3, fill the ice cube of studied use, position between ice cube is provided with temperature sensor 4, and this temperature sensor 4 sends the variations in temperature data of ice cube to outside data record and treatment facility (not shown) by wire.
Water is injected between the uncovered bottle 3 of the first uncovered bottle 2 and second, and the water being injected into is to the ice transferring heat in the second uncovered bottle 3, the ice in the second uncovered bottle 3 gradually become water.In this process, the shortcoming 2 of carrying above to shortcoming 5 still exists, but the more important thing is, because ice cube is solid, so temperature sensor 4 can not with ice cube close contact, cause temperature that temperature sensor 4 reads higher than the actual temperature of ice cube.
Therefore, be necessary to invent a kind of experimental tool external member that can present important liquefaction and curing phenomenon in fact, to overcome the defect of prior art.
