Model Description This is a demonstration of the basic principles open and closed systems. It reinforces the conservation of mass and energy. This demonstration should take 5-8 minutes. Engineering Principle Most students have a basic understanding of open and closed systems, but tend to get lost in the terminology. In order to assist in the […]
Model Description This is a demonstration designed to generate a conceptual discussion about the 2nd Law of Thermodynamics and the Kelvin-Planck statement of the law in particular. It utilizes a pendulum to introduce the concept of irreversibilities due to friction. This demonstration should take 10-15 minutes. Engineering Principle This demonstration is based on the assumption […]
Model Description This demonstration illustrates the material property of thermal conductivity, and how this property affects conduction heat transfer in a solid. Concepts include Fourier’s Law, conservation of energy and solid-liquid phase change. This demonstration should take 8-10 minutes. Engineering Principle Fourier’s Law states that the heat transfer rate in a solid is proportional to […]
