Abstract
The utility model discloses an apparatus for demonstrating the comparison between the heat absorbability of a dark object surface and the heat absorbability of a light object surface, which belongs to a physics experiment demonstration apparatus in middle schools and has an evident experimental effect. The apparatus comprises a base. The structure of the apparatus has the following characteristics: a framework of the same material is arranged upon the base, sensors are respectively arranged on both sides of the framework, a black surface and a white surface are respectively painted on both sides with the center of the framework as a boundary, a bulb is arranged at the center in the framework, and digital thermometers are respectively arranged at both sides of the bulb.
Description
Technical field:
The utility model is to belong to the middle school physical experiment apparatus for demonstrating.
Background technology:
How traditional dark object surface and light color matter surface heat absorption contrast apparatus for demonstrating feel that with feel DeGrain is not received good teaching efficiency.
The utility model content:
The utility model is exactly at the problems referred to above, and the tangible dark object of a kind of experiment effect surface and light color matter surface heat absorption contrast apparatus for demonstrating are provided.
For achieving the above object, the utility model adopts following technical scheme, and the utility model comprises base, its structural feature base top is provided with the framework of same material, be respectively arranged with sensor on the both sides of framework, the center of framework is the boundary, and both sides scribble black surface and white surface respectively; Center in the framework is provided with bulb, and the both sides of bulb are respectively arranged with digital thermometer.
The beneficial effects of the utility model:
The utility model makes the heat absorption of black surface and white surface by the irradiation of bulb, shows the strong principle of dark object surface ratio light color matter surface heat absorption.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model comprises base 1, and base 1 top is provided with the framework 4 of same material, is respectively arranged with sensor 2,9 on the both sides of framework 4, and the center of framework 4 is the boundary, and both sides scribble black surface 3 and white surface 8 respectively; Center in the framework 4 is provided with bulb 6, and the both sides of bulb 6 are respectively arranged with digital thermometer 5,7.
During use, energized at first, bulb 6 is emitted heat, black surface 3 absorbs heat simultaneously with white surface 8, black surface 3 is passed to digital thermometer 5,7 with two sensors 2,9 of white surface 8 with the heat absorption situation, connect black surface 3 digital thermometers 5 temperature-rise ratios and connect the rising of white surface 8 digital thermometers 7 temperature soon, show that dark object surface heat absorption capacity is strong.
