Factors Affecting Diffusion Diffusion Lesson 3 Basic Knowledge

Factors Affecting Diffusion Diffusion Lesson 3 Basic Knowledge Factors affecting the rate of diffusion. key stage 3 worksheet on factors that ef fect the rate of diffusion. in this activity, students put a series of particle pictures in order of diffusion rate. the idea of this task is that it (hopefully!) will illicit the idea that the rate of diffusion depends on temperature and particle size. thinking. Electricity moving through a wire. heat moving through a metal rod. q3. diffusion happens more quickly at higher temperatures because particles have more energy in their energy store. kinetic. q4. match the adaptation of alveoli to the explanation. folded structure . increases surface area.
