Abstract
In early graduation, frequently it is observed a lack of motivation to study Thermodynamics or Chemical-Physics without a direct contact with in locus experiments that demonstrate the necessary understanding of these great themes. This perception and the finding that the burning of cotton or small pieces of paper in a transparent pneumatic lighter – witch, in turn, is a qualitative experiment of great simplicity and of rapid execution in classroom – calls attention of the students for these areas of knowledge, gives the basis for this work. So, we wish in this presentation to stimulate further contact between quantitative physical and qualitative chemical methods for investigation about the mater structure and the technical and technological applications of this. We want to give a so desired reason for students to pay attention in basics physics and chemistry.
