Pictorial Procedure
Boyle’s Law:
Connect the syringe through the Tygon/nylon tube to PhysBar. The PhysBar module is connected to Channel C of the Physlogger. There is also a need to make the connection of the Vcc (%V terminal) to the leftmost pin of Physlogger. The pressure data appearing in Channel 3 of the Physlogger app.
Amonton’s Law:
The copper coil is connected to Physbar. Physbar is connected to Channel C of Phsylogger in the usual way (refer to the section on Boyle’s law). The copper coil is immersed in about 150 mL of water inside a 250 mL beaker and placed on a hot plate. A probe thermocouple is introduced inside the coil. The Thermocouple is attached to Physlab Thermocouple module and the amplified output from this module reaches Channel A of Physlogger. An additional 5V connection needs to be done on the provided terminal of Physlogger.
Charles’s Law:
In this part of the experiment, the copper coil is connected to a flexible tubing with a plastic tee at the other end. The tee has three ports. One port goes to the copper coil. The second part is exposed to PhysBar. The third part is connected through another flexible tubing to the syringe. The piston of the syringe can lift a 3D printed manipulator that makes contact with PhysDisp, Physlab’s linear displacement transducer.
The electrical connections of the thermocouple and PhysBar to Physlogger remain unchanged. PhysDisp is connected to the ID and IC (Instrument Data and Instrument Current) channels of PhysLogger while the GND terminal is connected to the empty G terminal in Physlogger’s Channel B. Channel B on the PhysLogger software can be configured to display the displacements recorded by PhyDisp.
