Combined equipment for researching ice melting point, water boiling point and specific heat capacity of liquid

Abstract

The invention discloses combined equipment for researching an ice melting point, a water boiling point and the specific heat capacity of liquid. The combined equipment comprises an iron stand, an alcohol lamp (8) and an asbestosed wire gauze, wherein the alcohol lamp (8) is arranged on an iron stand base (9). The combined equipment is characterized in that the upper end of the iron stand is movably connected with a connecting rod, wherein an iron block (4) is welded on the connecting rod; a digital temperature meter display screen (1) is arranged on the iron block (4); a 9V motor power supply (2) and a switch are arranged behind the digital temperature meter display screen (1); the digital temperature meter display screen (1) is connected with a temperature meter probe (6); the 9V motor power supply (2) is connected with a stirring connecting rod (5) below the iron block (4); a stirring impeller (7) is arranged at the bottom end of the stirring connecting rod (5). According to the combined equipment, three experiments can be made more simply and intelligently, time is greatly saved for the experiments, and the classroom efficiency is improved.

Description

technical field [0001] The invention belongs to a teaching experiment device, in particular to a combined device for exploring the melting point of ice, the boiling point of water and the specific heat capacity of liquid. Background technique [0002] In the process of learning physics, there will be many experiments, and various glass instruments will be used, such as beakers, glass rods, test tubes, thermometers and other fragile items. There are glass instruments in the three experimental devices that explore the melting point of ice, boiling point of water, and specific heat capacity of liquids. If you are not careful, it is easy to break these glass instruments and hurt your fingers. In addition, when doing these experiments, I also found that the process of assembling the experimental equipment was too troublesome. The thermometer had to be hung with a thin wire, and the heating process had to be stirred continuously, which was very laborious. Third, these three exper...

Problems solved by technology

There are glass instruments in the three experimental devices that explore the melting point of ice, boiling point of water, and specific heat capacity of liquids. If you are not careful, you can easily break these glass instruments and hurt your fingers.

In addition, when doing these experiments, I also found that the process of assembling the experimental equipment was too troublesome. The thermometer had to be hung with a thin wire, and the heating process had to be stirred continuously, which was very laborious.

Third, these three experiments all require a thermometer, and in order to reduce the error in each reading, the line of sight must be level with the liquid level, not to mention time-consuming and laborious, and the reading error is also relatively large
