Ideal Gas Law Apparatus

Product Code: TD-8596A


Investigating the Ideal Gas Law is simple using PASCO’s Ideal Gas Law Apparatus. By connecting a Pressure Sensor and a Temperature Sensor to the syringe, students can quantitatively look at the relationships between pressure, temperature, and volume.

The large syringe ensures accurate volume measurements and the stable design (updated for 2010) means consistently repeatable results as well as long term reliability.


  • Discover or verify the Ideal Gas Law
  • Investigate relationships of pressure vs. temperature (Gay-Lussac’s Law)
  • Investigate relationships of pressure vs. volume (Boyle’s Law)
  • Investigate relationships of temperature vs. volume (Charles’ Law)
  • Calculate the number of moles of air in the syringe based on pressure, temperature and volume measurements

How It Works

A low thermal mass thermistor is mounted within the syringe for real-time measurement of temperature changes inside the syringe. Tubing and a quick-connect port allow a Pressure Sensor to be directly connected to the syringe. As the plunger of the syringe is depressed, the volume decreases while pressure and temperature increase. The data will help students better understand the Ideal Gas Law.

PV = nRT

A mechanical stop is included on the syringe plunger to prevent damaging of the thermistor within the syringe and to allow quick (adiabatic) volume changes.
