Change of State of Gases Apparatus

1. Experimental investigation of gas laws
2. Transparent measuring vessel 1 for investigation of isothermic change of state
3. Hydraulic oil filling for changing volume of test gas
4. Built-in compressor ensures necessary pressure differences to move the oil volume
5. Compressor can also be used as vacuum pump
6. 5/2-way valve for switching between compression and expansion
7. Transparent measuring vessel 2 for investigation of isochoric change of state
8. Electrical heater with temperature control in vessel 2
9. Sensors for temperatures, pressures and volumes
10. Digital displays for temperatures, pressures and volumes
