In this note we present some remarks on the prediction of the equilibrium state in a horizontal, rigid, adiabatic cylinder divided into two chambers by an adiabatic piston. The two chambers contain two gases 1 and 2, at different pressures and temperatures. […]
This article underlines the importance of being aware of heuristic abilities to be used in solving problems of Physics, suggests a reasoned inventory of these and proposes two strategies aimed at strengthening specific heuristic abilities. […]

In Russia there’s an old and consolidated tradition associated with Physics problems and exercises for students, as the very famous section “Zadaci po Matematike i Fizike” (“Mathematics and Physics problems”) of “Kvant” magazine shows. This article presents all the problems on various school levels that were assigned during the 28th Russian Olympiads for Physics (1994), […]
Lately the interest in International Olympiads for Physics has been greatly increasing throughout Portugal. As a matter of fact, the Portoguese Physics Society (SPF) signed a document concerning a formal agreement with Portugal central Government for the organization of Regional and National selection tests. […]
Physics examination papers, which were set during the latest (1984) “Concorsi” (i.e. the competitive examinations through which the teachers applying for positions in the Italian State Schools are selected) for teaching “Physics” and “Mathematics and Physics” at secondary school level, are here briefly commented on and a possible solution is sketched for two of the problems. […]
In 1998 a book was published in which some physics problems from oral admission examinations at Ecole Normale Sup6rieure in Cachan (France) were collected. These are all problems dealing with physical phenomena of our daily life, used to investigate the ability of candidates in constructing a good model of different physical situations. […]
Four problems are discussed giving’ a schematic solution and an evaluation. […]
This article presents the physics problems set for the written tests of the final examinations in the experimental secondary schools in 1991. We offer a possible solution and a short comment. […]
Two problems are discussed, giving a schematic solution and an evaluation […]
