Abstract

The relationships between the properties of gases are not mere "curiosities" and have important implications in areas such as chemistry, chemical engineering, materials science and engineering, mechanical engineering, aerospace engineering, meteorology, etc. In the present  work, we describe a practical device to study the pressure – air temperature relationship in constant volume that can be built and tested by students in the first years of science courses. The simplicity and reliability of the device make the proposal effectively capable of being used in experimental practices in several high school courses, or even in higher education and even in teacher training courses.
