Trasformazione termodinamica isoterma on-line: un’occasione per discutere la realizzazione e la taratura di un trasduttore di volume

This paper presents a simple educational on-line experiment about gas (air) transformation. This experiment was performed using an intelligent serial interface (ULI) and a volume transducer designed for this purpose. The paper is divided into two parts: the first explains the design and the calibration of the volume transducer, the second gives some practical hints for performing the experiment during a physics class.
