Diffusion
Diffusion
The movement of particles from a region of higher concentration to a region of lower concentration.
Temperature and Diffusion
Temperature and Diffusion
Higher temperatures cause particles to move faster, leading to more frequent collisions and faster spreading.

Study Notes
Temperature Affecting Diffusion
- Temperature increases the rate of diffusion.
- An example is an incense stick; the smell is noticeable closer to the stick but also detectable further away if the stick is lit.
- Diffusion increases with heating because of the kinetic energy of particles.
Comparing Liquid Diffusion Rates
- Liquids with higher density diffuse slower than liquids with lower densities.
- An experiment involves placing blue ink in one beaker of water and honey in another beaker of water.
- The blue ink diffuses faster than the honey.
- The conclusion is that the density of the liquid affects the speed of diffusion.
Diffusion Rate Variation with Temperature
- An experiment using copper sulfate, cold water, and hot water shows a relationship between temperature and diffusion rate.
- Copper sulfate dissolves faster in hot water.
- The conclusion is that a higher temperature accelerates the rate of diffusion.
Gases Diffusing in Liquids
- Oxygen and carbon dioxide are dissolved in water, essential for the growth of aquatic life.
Gas Compression
- Gases are more easily compressed than liquids.
- The experiment uses two 10ml syringes, a rubber cork, and vaseline to close the syringe nozzles.
- The air is allowed to fill the space inside one syringe and the other syringe is filled with air from the other.
- The conclusion is that gases are compressed more easily than liquids.
