A non-mathematical outline of thermodynamics

Robert H.B. Exell

<p><strong>Abstract: </strong>A simple qualitative presentation of the laws of thermodynamics is given for non-specialists without using mathematics.
Descriptions of the properties of a thermodynamic system are given in terms of the random motion of the particles in the system. It is
shown how the Principle of Conservation of Energy and the First Law lead to the concept of internal energy and the State Principle.
The Second Law is divided into two parts. The first part is concerned with entropy and thermodynamic temperature. Entropy is an
indicator for the possibility of adiabatic changes between equilibrium states. Thermodynamic temperature is an indicator for the
internal energy of equilibrium states. The second part of the Second Law is the Principle of Increase of Entropy, which states that
when coupled systems move spontaneously from disequilibrium to equilibrium with each other, the total entropy of the systems
increases. The Third Law states that no finite process can cool a system to the absolute zero of temperature.

Publishing research in a journal

Shabbir H. Gheewala

<div style="text-align:justify;"><span style="color:#000000;"><strong>Abstract:</strong> Publishing research results in peer-reviewed journals is an important part of the academic process. There is both science and
art involved in the entire publication process, starting from writing the manuscript, through the review process, revision, and ultimately
the final acceptance. Based on the experience of the author of this article as an author, reviewer, and journal editor, information is
provided on all these aspects in involved in publishing a journal paper. Special tips are provided on writing manuscripts, selecting
journals, and handling the review process.</span> </div>
