Ideal Gas Law

Introduction

The Ideal Gas Law Apparatus, TD-8596A, allows simultaneous

measurements of temperature and pressure of a gas as it is com-

pressed. A low thermal mass thermistor is built into the base of

the syringe to measure temperature changes inside the syringe.

The response time is around 0.5 second. The plunger is equipped

with a mechanical stop that protects the thermistor, and also

allows for a predetermined change in volume. The apparatus has a

mini stereo plug temperature connector that connects directly to a

port on a temperature sensor and a quick-release pressure connec-

tor. As the plunger of the syringe is depressed, the volume

decreases while pressure and temperature increase. NOTE: This

experiment requires the “A” version of the Ideal Gas Law Appara-

tus.

Equipment Setup

Use the Hydraulic Boom structure with the Ideal Gas Law Apparatus (TD-8596A) and the Pressure/Temperature

Sensor (PS-2146).

• Unscrew the male luer lock at the base of the Ideal Gas Law (IGL) Apparatus to remove the short

quick-release connector from the apparatus.

• Connect the Pressure Sensor Coupler to the female luer lock on the base of the IGL Apparatus in place of the

quick-release connector.

• Connect the side arm of the Pressure Sensor Coupler to the pressure port on the Pressure/Temperature

Sensor.

• Connect the Syringe Coupler from the Pressure Sensor Coupler to the Hydraulic Cylinder.

• Plug the mini stereo plug of the Temperature Connector from the IGL Apparatus into the

temperature port on the Pressure/Temperature sensor.

• Plug the Pressure/Temperature Sensor and the Rotary Motion Sensor into a

PASCO Interface. (NOTE: You may want to use a PASport Extension

Cable to connect the Pressure/Temperature Sensor to the interface.)
