The Difference between Total and Inexact Differential Using 3D Printing Technology and LEGO© Bricks: Application on the First Law of Thermodynamics

Abstract

The poster presents two educational kits created with the help of 3D printing technology. Both kits are used as a part of the course of advanced thermodynamics aimed specially at future high school teachers.

The kits deal with multivariable differential, emphasizing the difference between total (exact) and inexact differential, and the First Law of Thermodynamics.
