EXPANSION OF A PERFECT GAS

The apparatus consists of two frame mounted interconnected transparent and rigid vessels, with one vessel equipped for operation under pressure and the second vessel under vacuum.

The vessel is pressurised and vacuumed using an electrical air pump together with valves and tappings.

The vessels are independent and can also be used together to enable the study of various thermodynamic processes. 

The apparatus includes VDAS® Onboard. A USB cable (supplied) connects the unit to a suitable PC (not supplied) running TecQuipment’s VDAS® software that captures, records and displays data. 

The software is intuitive and easy to use, with clear and convenient data display options. It looks similar and works in a similar way for each TecQuipment VDAS® compliant product. This saves time as students do not have to learn to use new software when changing experiments. 

VDAS® gives accurate real-time data capture, monitoring and displaying of all key readings, calculation and charts on a computer (not included).

Key features:

• Includes TecQuipment’s Versatile Data Acquisition system VDAS® Onboard, for data acquisition via USB
• Benchtop experiment for convenient use in a laboratory
• Highly visual experiment with accurate and repeatable results
• Simple and safe to use, needs no tools
• Supplied with an electric pump for easy compression and decompression of the gas (air)
