Background technology
The rule of gas hot expanding type is more complicated, when the volume hand temperature of certain mass gas influences to rise variation, pressure
It is strong that it can also happen that changing, if keeping pressure inconvenient, when temperature raises, volume becomes larger, and when volume inconvenience, gas is heated
After expand, pressure becomes larger, due to gas molecular motion more acutely and molecule is apart from bigger, so what gas was expanded when heated
Volume ratio solid and liquid are much bigger.In teaching, generally by test tube opening bottle stopper beyond the Great Wall, it is subsequently sandwiched on iron stand and uses wine
Smart lamp heating, after a period of time is heated, gas expansion pops up bottle stopper；Also a kind of demonstration equipment is that flask is covered bottle
It fills in, then an embedded glass tube on bottle stopper, the colored marker in one end or injection beyond the Great Wall is with color in glass tube
Water droplet, then by flask put in the hot water, observe glass tube in marker or water droplet movement.Which kind of experiment method is all deposited
Experiment method it is single, can not disposably observe what multiple gases expanded by heating situation and different temperatures influenced gas expansion
Problem.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide and plurality of liquid is set together and can
Observe a kind of gas with various expanded by heating apparatus for demonstrating of the different temperatures to liquid expansion effects.
The technical scheme adopted by the utility model is that：
A kind of gas with various expanded by heating apparatus for demonstrating, it is characterised in that：Including square box, cover board, test tube and heating rod, side
Box upper end spiral-lock cover board, cover board make multiple perforates by one side to opposite side, a rubber ring, each rubber are set in each perforate
Bottle stopper is installed in one test tube of clamping in rubber ring, each test tube upper end, and each bottle stopper is embedded in a communicating pipe, which is located at
A pressure sensor is installed in upper end above test tube, and the output terminal of each pressure sensor is all connected with a host computer, each bottle
An air inlet pipe for carrying valve is also set up beyond the Great Wall, and filling gas and lower end are located at the liquid level for the water filled in square box in all test tubes
Lower section sets one in square box bottom for heating the heating rod of water.
Moreover, cover board both ends set a bolt, which is used to cover board and square box being fixed together.
Moreover, setting a gas outlet on each bottle stopper, a pressure release is installed in the upper end which is located above bottle stopper
Valve.
Moreover, the forepart of the square box is embedded in a transparent glass.
Moreover, the outlet of each relief valve passes through one gas sampling bottle group of pipeline connection.
Moreover, an exhaust pipe is embedded on the cover board.
Moreover, setting a thermometer on the cover board, the lower end of the thermometer is located at below the liquid level of the water in back box.
Moreover, outside bending edges are made in each rubber ring top and bottom, two bending edges are crimped on cover board respectively
Upper surface and bottom surface.
The advantages of the utility model and good effect are：
In the utility model, multiple test tubes are embedded in the rubber ring of cover board, air, dioxy can be filled in these test tubes
Change the gases of different nature such as carbon, nitrogen, argon gas, chlorine, gas is poured into various gases by air inlet pipe first, is then shut off
Inlet tube and two valves of communicating pipe, test tube is closed, and can start to test after installing pressure sensor.When in square box
When water temperature raises, due to test tube constancy of volume, after gas expansion the output of pressure sensor can increase, these data can lead to
Host computer is crossed to show, with the continuous rise of water temperature, pressure value constantly rises, and when gas expansion is excessive, relief valve is opened,
Gas enters gas sampling bottle by pipeline, since each gas hot expanding type coefficient is different, so the variation of pressure value is also different,
Thus student's intuitively more different coefficients of expansion situation that when gases are heated, they expand is allow, it can also be intuitively more different
At a temperature of each gas expansion situation, easy to use, experiment effect is good.
