The Effect of Molecular Weight and Time on the Diffusion Rate of Potassium Permanganate‚ Potassium Dichromate‚ and Methylene Blue.1 Arantxa Alex Carpio Group 1 Sec. X – 4L March 24‚ 2015 ABSTRACT The effect of molecular weight and time on the rate of diffusion was determined using the agar-water gel test. A petri dish of agar-water gel with three wells was prepared and a prepared solution of each substance was dropped on each well; one with potassium permanganate (KMnO4)‚

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

understanding on how osmosis and diffusion works. In its simplicity‚ it explains the process that our bodies (mainly cells) use all the time. It also showed me that even with the temperature changing‚ it doesn’t drastically change the rate of diffusion. Introduction Diffusion is important in all living systems. Osmosis is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration (Purchon 1). Diffusion is the movement of a substance

"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

A summary of Diffusion of Innovations Les Robinson Fully revised and rewritten Jan 2009 Diffusion of Innovations seeks to explain how innovations are taken up in a population. An innovation is an idea‚ behaviour‚ or object that is perceived as new by its audience. Diffusion of Innovations offers three valuable insights into the process of social change: - What qualities make an innovation spread successfully. - The importance of peer-peer conversations and peer networks.

Between the years 600-1450‚ the civilizations in Europe and West Asia further developed their individual empires and displayed much growth and influence. Socially‚ both regions developed patriarchal societies‚ but had different social structures. Culturally‚ Europe and West Asia received outside influences and effectively spread their religions. Economically‚ they interacted with other regions to enhance their societies. Thus‚ the social‚ cultural and economic aspects helped give rise to interaction

Briefly describe the difference between intrapersonal and interpersonal approaches. What are the advantages and disadvantages of both? The difference is that interpersonal refers to relationships or actions that take place between two or more people while intrapersonal refers to things that go on exclusively within one person. Inter is a prefix meaning between. Similarly‚ we have interpersonal relations that are between two or more people. Intra is a prefix meaning within. In schools‚ we sometimes

of the cell. An important part of regulating this is passive transport. Passive transport is the movement of materials through membranes without any input of energy. One type of passive transport is diffusion. Passive transport is the diffusion of substances across a membrane. In diffusion‚ molecules will usually move from where the substance is more concentrated to where it is less concentrated. The molecules also tend to spread out in the space they enter just like food coloring in water
