Competency-Based Learning. Teaching Gases

This paper seeks to evaluate learning based on the competency approach, taking a didactic experience to evaluate a possible improvement in the ability to solve problems and for autonomous learning in general. For the didactic development, the theme "gases" was taken, which is generally enunciated: Corpuscular kinetic theory of matter; State variables of a gas: P, V, T; Absolute temperature; General and State Equation of Ideal Gases Dalton's Law or Law of Partial Pressures; Ideal Gases and Real Gases; Van der Waals equation. For this purpose, the AIRBAG systems, and the determination of the normal molar volume of a gas are taken as the object of study.
