t is shown at a level suitable for an undergraduate student that thermodynamics can be use to deal with certain thermal systems out of equilibrium. The trick is to cut the system in parts or slides small enough so that the thermodynamics magnitudes h

An apparent paradox in hydrostatics

It is shown that for a liquid in any connected vessel system, it is not possible to fulfil simultaneously Pascal's principle, mass conservation and energy conservation. The viscosity has to necessarily be taken into account to understand the system c

What lies between a free adiabatic expansion and a quasi-static one?

Autor: E. N. Miranda

An expression is found that relates the initial and final volumes and temperatures for any adiabatic process. It is given in terms of a parameter r that smoothly interpolates between a free adiabatic expansion (r = 0) and a quasi-static one (r = 1).

The motion of a projectile with horizontal initial velocity V0, moving under the action of the gravitational field and a drug force is studied analytically. As it is well known, the projectile reaches a terminal velocity Vterm. There is a curious res

A paradox in the electronic partition function or how to be cautious with mathematics

Autor: E N Miranda

Publikováno v: European Journal of Physics. 22:483-485

When the electronic partition functions of atoms or molecules are evaluated in textbooks, only the contribution of the ground state is considered. The excited states' contribution is argued to be negligible. However, a closer look shows that the part
