EXPERIMENT 5 GAS DIFFUSION COEFFICIENT OBJECTIVES: Determine the gas diffusion coefficient of acetone using the established Winkelmann’s method KEYWORDS Diffusivity‚ Gas Diffusion Coefficient‚ Winkelmann’s method OVERVIEW The knowledge of physical and chemical properties of certain materials is important because very often process engineering deal with the transformation and distribution of these materials in bulk. One such property is diffusivity. Mass transfer by diffusion takes

OPTION A - SIGHT AND WAVE PHENOMENA 1. Standing (or stationary) waves Formation of standing waves : When two identical waves travel along a string in opposite directions (ex : flick a rope attached at the other end)‚ they will superpose and create a standing wave (use animation to visualize what happens). Nodes‚ antinodes. Differences between progressive and standing waves : Wave profile doesn’t progress ; All points between two nodes are in phase (they all reach their maximum at the

The Natural Review The Natural is a fantasy like story of a middle-aged pitcher trying to make one last comeback as a right fielder for the New York Knights. Directed by Barry Levinson and starring Robert Redford as Roy Hobbs‚ The Natural is a feel good movie that is hardly believable at times‚ but does a lot to provide a worthwhile movie experience. In today’s movie review I will illustrate what I think this movie does well in terms of viewer enjoyment‚ while analyzing specific themes such as the

“What are the major strengths and weakness of Dworkin’s theory of law as compared to a positivist or natural law perspective?” Discuss. Arguably one of the most influential legal theorists of the 20th century‚ Ronald Dworkin’s dealings with law’s interpretation and integrity has lead to inevitable contradictions with that of positivist ideology‚ with his work essentially revitalising a method of thinking that had long been considered dead and buried. Perhaps most notoriously‚ Dworkin combated

Natural disasters are often not natural disasters‚ but are in fact human disasters. Discuss this statement in relation to seismic events. The word ‘natural’ indicates that humans have not caused the disaster. However‚ human activity can certainly interfere with nature‚ which in turn may either cause a natural disaster or make its effects much worse. Earthquakes can affect people in many different ways in countries all over the world. They are a product of intense seismic activity where plates are
