Anno XXIV - n.2 - aprile/giugno 1991 Gas perfetti e gas reali. 1° Premio: Liceo Scientifico Statale “A. Tassorlin, Modena
We begin to study the properties of gases through a well-known mechanical model, then we perform a school-Iab replica of Volta’s experiment on the dilatation of gases at constant pressure. After observing that the behaviour of air is close to that of ideal gases, […]
Anno XXIV - n.2 - aprile/giugno 1991 Gas perfetti e gas reali. 2° Premio: Liceo Classico “Virgilio”, Empoli FI
A few experiments on the behaviour of real gases were performed. They show that the behaviour of air at constant temperature is quite similar to that of an ideai gas but, at constant pressure and varying temperature, the different behaviours of various gases (air, […]
Anno XXVI - n.1 - gennaio/marzo 1993 Geometria dello spazio-tempo e paradossi relativistici
The classical skier paradox is revisited, with the aim of showing that a strictly geometric approach (i.e. one that makes no use of Lorentz transformations and the like) is more apt at revealing the true nature of the physical problem being studied. […]
Anno XLII - n.2 - aprile/giugno 2009 Giochi di equilibrio
Equilibrium is an obvious topic in physics: it is interesting, not too difficult and it has many applications. But, as quantitative experiments are few, it is not always presented in lab sessions. The paper presents a variety of devices on which a problem solving oriented session might be based. […]
Anno XLIII - n.2 - aprile/giugno 2010 Giochi ed esperimenti con le bottiglie di plastica
Some simple low cost demonstrations using plastic bottles of mineral water are reported. The experiments explore the pressure and weight of gases, Archimede’s law, gases dissolved in water, the Cartesian diver and other phenomena. […]
