Change of State of Gases
Product Code : JA-FMAHLE-9978
The Change of State of Gases unit (SKU JA-FMAHLE-9978) is used for experimental investigation of the gas laws. One transparent tank is used for isothermal changes of state and a second, heated tank for isochoric changes, with the gas volume changed by moving hydraulic oil. JaincoLab supplies this gas laws apparatus to engineering colleges and polytechnics for thermodynamics practicals, with sensors and digital displays for temperature, pressure and volume.
Specifications
A built-in 60 W compressor, which can also work as a vacuum pump (outlet 2 bar, inlet 213 mbar), moves the oil volume through a 5/2-way valve; tank 2 has an electrical heater with PID control (300 W, limited to 80 °C), and sensors display temperatures, pressures and volumes.

Experiments on the change of state of gases unit
The change of state of gases unit lets students hold temperature or volume constant while changing the other variables, so they can verify the gas laws from measured pressure, volume and temperature, a standard experiment in thermodynamics and physics of gases courses.
- Investigating an isothermal change of state (pressure against volume)
- Investigating an isochoric change of state (pressure against temperature)
- Experimental verification of the gas laws
- Thermodynamics practicals in B.E./B.Tech, diploma and B.Sc courses
