DIFFUSION RATE OF DIFFERENT SOLVENTS 1. Objective The aim of this experiment is to find how different solvents with different molar mass affect the time taken for a substance to diffuse with the solvents. 2. Hypothesis Different solvents have different molar mass. The lighter the particles in the solvent are, the faster it is to diffuse. If the temperature was high then the rate of diffusion was ... If the temperature was high, then the rate of diffusion was higher because it took longer for the particles to reach the equilibrium when they were exposed to higher temperatures. B. Why do you think this was the case? When the temperature is high the particles expand and because they are moving at a fast rate and bouncing off of the walls of its boundaries, it takes a longer time for … Factors affecting diffusion practical 1 temperature - Issuu Jun 06, 2014 · Investigating diffusion. Diffusion is the spreading of the particles of a gas, or of any substance in solution, resulting in a net movement from a region where they are of higher concentration to What are two ways to increase the rate of diffusion - Answers The rate of diffusion through a membrane is also directly proportional to the surface area of the membrane, which can be increased by such adaptations as microvilli. What two ways …

Diffusion is the movement of particles from a high to lower concentration. Osmosis is the diffusion of water across a membrane. Active transport moves … What Factors Affect the Rate of Diffusion? | Reference.com Rate of diffusion is influenced by several factors including temperature, concentration difference and particle size. The diffusion rate is also affected when there is a change in distance between the points where diffusion occurs. Diffusion rates and concentration investigation | Teaching ...

Osmosis and Diffusion Lab Saagar Chitale 10/13/14 AP Bio Pd.5 Introduction: The first part of this three part lab was an investigation that examined the relationship between rate of diffusion and the surface area to volume ratio. Diffusion and Osmosis Lab by Karina Lukovits on Prezi Cell 1 had the greatest SA/V Ratio, and had the lowest diffusion efficiency even though it diffused the fastest. Cell 2 had the smallest SA/V Ratio and highest diffusion efficiency. Cell 3 took the longest time to diffuse, but had a diffusion efficiency and SA/V ratio that was in Biology Diffusion Experiment Essay - Topics, Sample Papers ...
