As trade along the Silk Road grew‚ Chinese weavers wanted to design silks that would appeal to other cultures. (Cultural Diffusion & the Silk Route of Ancient China) Some examples of this are the silk rugs called “ The Tree of Life‚” that reflected upon the Persian culture. This rug contained the roundel animal symbol and scenes of saddled horsemen. They used thread wrapped

Osmosis and diffusion are sometimes mixed up without much thought‚ but they are very different in many ways. Osmosis is a defined as the movement of water through a semipermeable membrane (). The membrane is fully permeable for the small water molecules‚ but is selectively permeable to any substance that is lager that a normal water molecule. One example might be a glucose and water mixture‚ when the solute is put into one side of a U-shaped tube that has a semipermeable membrane between the solvent

Name: Leslie Estrada Exercise 1: Cell Transport Mechanisms and Permeability: Activity 1: Simulating Dialysis (Simple Diffusion) Lab Report Pre-lab Quiz Results You scored 100% by answering 4 out of 4 questions correctly. 1. The driving force for diffusion is You correctly answered: b. the kinetic energy of the molecules in motion. 2. In diffusion‚ molecules move You correctly answered: a. from high concentration to low concentration. 3. Which of the following dialysis membranes has the largest

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

Jean Perrin‚ a French physicist who later won the Nobel prize‚ spring boarded off of Einstein’s work. Using Brownian motion as evidence‚ he proved in 1911‚ once and for all‚ that matter is made of atoms and molecules. Diffusion Diffusion‚ also called molecular diffusion‚ is the process by which molecules of a given substance move from an area of relatively high concentration to an area of lower concentration. When the molecules have diffused so that they are in a uniform concentration‚ this

Lab One – Diffusion and Osmosis SECTION ONE: Methods Lab 1 – Diffusion and Osmosis can be broken down into four parts (A‚ B‚ C‚ and D). Lab 1A – Diffusion In this exercise‚ we tested diffusion through dialysis tubing. This was done through a demo with the teacher‚ rather than individually in groups. First‚ a piece of 2.5cm dialysis tubing was obtained. Then one end was folded and clipped securely so that a solution poured into the bag would not leak out. Next‚ the other side of the bag was

Purpose: The purpose of this lab is to test the effects of osmosis on eggs in hypertonic solutions and hypotonic solutions. Hypothesis: If the corn syrup is a hypertonic solution‚ then the egg’s size will shrink. If the water is a hypotonic solution‚ then the egg will swell. Materials: Styrofoam cups (2 per group) Styrofoam cups to weigh down egg (2) Balance Paper towels Vinegar (enough to cover egg) Distilled water Corn syrup Fresh eggs (2 per group) Procedure: Day

The Rate of Diffusion in Different Temperatures Purpose: To see if the temperature of a solution will change the rate blue diffuses in it. This will be tested by timing how long it takes dye to diffuse in warm water‚ cold water‚ and room temperature water. Hypothesis: I think that the dye will diffuse at a faster rate in the warm water than in the cold water. I believe that the room temperature water will have the dye diffuse faster than the cold water but slower than the warm water. Variable:

6. Evaluation of Starbucks social responsibility strategy? Is it sincere? In assessing Starbucks Social responsibility strategy‚ one would have to look at certain key elements of the strategy and what makes it a good strategy‚ a great strategy or even a poor strategy. One would have to ask question such as; * When was the social responsibility strategy adopted? * Did the social responsibility strategy contribute to Starbucks success? * Has the strategy been used to defeat more resourceful
