Experimental instrument for the physical adiabatic compression and expansion

摘要

The present design relates to the physical test parish for adiabatic compression expansion.; In thermodynamics that can be referred to the basic physics of this vaporized material to be subjected during the adiabatic compression and expansion, the liquefaction of the phenomenon occurs. By this way to facilitate better understanding of this phenomenon into an alcohol or water to a particular vessel to remove air in the low pressure or to a high pressure of the liquid material inside showing the visual effectiveness hameuroseo observed a phenomenon in which vaporized or liquid have. These devices should be conducted separately for each job called adiabatic compression and expansion, expensive scientific equipment can proceed simultaneously in the students difficult to buy in the front-line education is staying the understanding of the thermodynamics theory.; The subject innovation is by a check valve to the inner container of transparent material, air-filled and to enable the suction at the same time, the inner temperature changes during operation of the pressure rise in the opposite of the injection of air hameuroseo installed measurable thermometer and the internal temperature and internal substances a phase change (相 變化) a) developed a laboratory adiabatic compression expansion precinct be visually observed.; The subject innovation is the one it continuously can be arbitrarily controlled from one and the same mechanism of the high pressure and low pressure at the same time, for example, the relationship, the experiment such as the pressure and temperature relationship with the sound transmission and air continuously from the high pressure down to a vacuum advances in the organization was able to observe the changes directly.
