Scientific Paper on Diffusion 2 ABSTRACT The effect of molecular weight on the rate of diffusion was assessed using two tests: the glass tube test and the agar-water gel test. In the glass tube set-up‚ two cotton plugs soaked in two different substances (HCl and NH4OH) were inserted into the two ends of the glass tube. The substance with the lighter molecular weight value (NH4OH‚ M = 35.0459 g/mole) diffused at a faster rate (dAve = 25.8cm)‚ resulting in the formation of a white ring around the

"Diffusion - How atoms move through solids" Diffusion means mass transport by atomic motion. The mechanisms of Gases & Liquids is known as random (Brownian) motion and for solids is known vacancy diffusion or interstitial diffusion. Simply we can define diffusion as‚ the movement of particles in a solid from an area of high concentration to an area of low concentration‚ resulting in the uniform distribution of the substance. (Diffusion chapter 5‚ 2008‚ p.1) Ronald D. Kriz(1999) suggests that

induction of new policies into a jurisdiction. The analysis of policy innovation and diffusion is important in explaining policy introduction and the non-incremental aspect of policy change. This paper is my response to the literature by Frances Stokes Berry and William D. Berry titled “Innovation and Diffusion Models in Policy Research” as well as the article by Charles R. Shipan and Craig Volden called “The Mechanisms of Policy Diffusion”. In this essay‚ I maintain that the unified model proposed by Berry
