Change of State of Gases Apparatus Model TH-102
Change of State of Gases Apparatus Model TH-102
* Isothermal and isochoric change of state of air
* Software for acquisition, processing and display of measured data
Item Description
Sci-tech Change of State of Gases Apparatus Model TH-102 unit enables two changes of state to be studied experimentally: isothermal change of state, also known as the Boyle-Mariotte law, and isochoric change of state, which occurs at constant volume. Transparent tanks enable the change of state to be observed. Air is used as the test gas. In the first tank, positioned on the left, the enclosed air volume is reduced or increased using a compressor and hydraulic oil. This results in an isothermal change of state. The compressor can also operate as a vacuum pump. If the changes occur slowly, the change of state takes place at an almost constant temperature. In the second tank, positioned on the right, the temperature of the test gas is increased by a controlled electric heater and the resulting pressure rise is measured. The volume of the enclosed gas remains constant. Temperatures, pressures and volumes are measured electronically, digitally displayed and transferred to a PC for processing.
