The Rate of Osmosis Investigation

... The Rate of Osmosis Introduction: - Molecules in a gas or liquid move continuously because they have kinetic energy -all particles posses' kinetic energy at temperatures above absolute zero (0 Kelvin or -273? Celsius). They move at random, bumping into each other and changing directions. So, they tend to diffuse, or spread, evenly in a gas or liquid. Therefore the kinetic energy associated with random motion is responsible for diffusion. Which is the net movement of particles (atoms, ions, and molecules) in a gas or liquid from a region of higher concentration to one of lower concentration until equilibrium (condition of no net change in the system) is reached. In other words, diffusion involves the net movement of particles down a concentration gradient. Diffusion is crucial in living organisms, but it is only efficient over distances of a few millimetres. This is because it is a very slow process. This is
