Abstract

The invention discloses a demonstrator for verifying an ideal gas state equation. The demonstrator comprises a piston 1 and a piston sleeve 2 with scales, wherein the piston 1 is arranged in the piston sleeve 2; a 50cm<3> transparent quartz glass box 4 is adhered to the lower end of the piston sleeve 2; the piston sleeve 2 is communicated with the transparent quartz glass box 4; the transparent quartz glass box 4 is adhered to the bottom of a large quartz glass container 3; a pressure gauge 6 and an electronic thermometer 7 provided with a lead probe are respectively fixed on a panel 5 and are respectively connected to the large glass container 3 through a rubber pipe and a wire. The demonstrator has the advantages that the operation is simple; an air pressure value can be directly read out from the pressure gauge 6 and a temperature value can be directly read out from the electronic thermometer 7, so that experiment is visual, accurate and convenient.

Description

Checking the Ideal-Gas Equation demonstrator
Technical field
The present invention relates to a kind of checking the Ideal-Gas Equation demonstrator.
Background technology
Directly do not verify the Ideal-Gas Equation fiber communication experiment demonstration instrument in current high school physics textbook, causing student to understand the study of this part has certain difficulty.
Summary of the invention
The object of the present invention is to provide a kind of checking the Ideal-Gas Equation fiber communication experiment demonstration instrument that can solve the problem.
For achieving the above object, the solution of the present invention is: make piston 1 with transparent quartz glass, and is with graduated piston bush 2, and piston 1 is contained in piston bush 2, is stained with a 50cm in piston bush 2 lower end 3transparency silica glass box 4, piston bush 2 and transparency silica glass box 4 communicate, quartz glass box 4 is bonded on the bottom of quartz glass bulk container 3, quartz glass bulk container 3 can fill the hot water of different temperatures, the electronic thermometer 7 of tensimeter 6 and band wire probe is separately fixed on panel 5, and they are connected to inside glass bulk container 3 with rubber tube and wire respectively.
Quartz glass has extremely low thermal expansivity, high temperature tolerance, fabulous chemical stability, excellent electrical insulating property, and has the mechanical property higher than simple glass, and therefore it is the good material making apparatus of the present invention.
Advantage of the present invention is easy and simple to handle, directly reads atmospheric pressure value with tensimeter 6, directly reads temperature value with electronic thermometer 7, makes experiment become directly perceived, accurately facilitates.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Wherein: 1 piston, 2 piston bushs, 3 bulk containers, 4 glass cases, 5 panels, 6 tensimeters, 7 electronic thermometers.
embodiment
Be closed gas for research object below with piston 1, directly read the pressure values being closed gas with tensimeter 6 p, read from the scale piston bush surface the bulking value being closed gas v, the temperature value being closed gas is directly read with electronic thermometer 7 t, calculate pV/ tvalue; Change be closed the volume of gas by promoting piston 1, change by the hot water filling different temperatures toward quartz glass bulk container 3 temperature being closed gas, read the experimental data of many groups of pressure being closed gas, volume and temperature, calculate and often organize pV/ tvalue, and compare, if equal in error range, the Ideal-Gas Equation is verified.
