Resumen

DOMINGUEZ, Orlando J; TORO, María A  y  SERRANO, Emilio M. THE TEACHING OF THE CONCEPT OF INTERMOLECULAR FORCES IN CHEMICAL ENGINEERING: THEIR RELATION TO MEASURABLE PROPERTIES. Form. Univ. [online]. 2014, vol.7, n.5, pp.15-22. ISSN 0718-5006.  http://dx.doi.org/10.4067/S0718-50062014000500003.

To facilitate the understanding of the concept of intermolecular forces which presents several difficulties as it requires the comprehension of processes occurring at molecular level. To do this, a lab experiment that enables to establish relationships between the different types of forces involved with the structure and macroscopic properties is proposed. Laboratory experiments are designed to measure a macroscopic property such as the surface tension for different substances, and relating these measurements with the interaction forces and their nature. Evaluation of the results using the knowledge acquired with the proposed didactic laboratory is done and results compared with classical theoretical learning. The proposed lab showed important improvements with respects to classical teaching.

Palabras clave : intermolecular forces; surface tension; didactic laboratory; engineering teaching.
