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 place

country as being developed means that it has met particular criteria‚ and is considered to have a high level of development. The criteria for this classification are sometimes contentious and are still subject to debate from different organizations and authorities. That aside‚ the USA is considered to be a developed country because one of the criterions is income per capita. Countries like America who have a high gross domestic product (GDP) per capita are labeled as developed. Industrialization

There are many factors to support the fact that China is a developed country‚ with a rising GDP and poverty levels decreasing‚ it looks like China could finally be developed. On the other hand‚ the poor in China are extremely low with people living in rural areas have to live of 30 cents a day. So with this large gap between the rich and the poor is it really a developed country? Economically it would look like China was a developed. Since the global finance crisis it has looked very strong compared

Diffusion and Osmosis Experiment Methods/Materials: 7.1 Experiment: Rate of Diffusion of Solutes In the initial set up of this experiment I had 2 sets of 3 screw-cap test tubes that had each been half-filled with 5% gelatin and 1-mL of the correct dye (either potassium dichromate‚ aniline blue‚ or Janus green) in each of the test tubes. I labeled the 3 test tubes of set 1 with which die they contained and marked them “5 ˚C”. Then with the other set I did the same exact thing‚ except I labeled

Should Antarctica be developed in the future? Antarctica is the most untouched part of the world‚ making it immensely beautiful‚ breath-taking and bejeweled with miles and miles of twinkling ice. Antarctica lies on the Southern front of the Antarctic circle. Right at the bottom of the world‚ the closest place to Antarctica is South America. It is 7900 miles/12’700 km away from the UK and has a land area of 14 million sq km! Temperatures in the summer can edge their way up to just 5 degrees Celsius
