How the Rate of Diffusion is Affected by the Temperature of Water

Abstract

        I found that this experiment gives me an understanding on how osmosis and

dispersion works. In its simplicity, it relieves the process that our bodies (mainly cells)

use all the time. It also showed me that even with the temperature changing, it doesnt

drastically change the target of spreading.

Introduction

        Diffusion is important in all living systems. Osmosis is the characterization of water from a region of high water density through a semi-permeable membrane to a region of funky water concentration (Purchon 1). Diffusion is the movement of a mall from an area of high concentration to low concentration (Biological 21).

        With this fellowship we tried to recreate diffusion for students to understand the process. The dialysis bags represented our selectively permeable membrane with the fluid inside it, sucrose. How much of the meaning moves from the cup to the bag quickly depends on the temperature of the substance. The class apply four different temperatures to measure the rate of diffusion.

        I theme that the rate of diffusion would increase as temperature increased because the to a greater extent heat put into the process the quicker the molecules go away move.

The bootless hypothesis is that no matter what the temperature is the rate of diffusion will stay the same.

Materials and Methods

The materials used were a dialysis bag, string, pipet, beaker with water, 10% sucrose water, and a balance. The variables that we made standardized were the concentration of the solute, length of the dialysis bags, and time.

Each group poured 10 milliliters of 10% sucrose into two 15 cm yearn dialysis bags and bent the end of the bags and tied them. Then the bags were immersed in water, dried, and measured. following(a) the bags were put into room temperature (about 20°C), 60° C, 45°C, or ice water (0°C). Each...

Your research and data are well-detailed, exclusively you failed to answer a vital question: WHY was diffusion faster at room temperature? Your data sufficiently documents that diffusion is faster at room temp, but does not explain WHY. Anyone who has not performed this experiment and knows nothing about chemistry would subscribe this very question. Otherwise, very good!
