Diffusion Flashcards
1
Q
Define diffusion.
A
The spreading out of particles from an area of higher concentration to an area of lower concentration until they are evenly spread out.
2
Q
In which state of matter do particles diffuse fastest? Why?
A
Gas. Because it will colllide with fewer particles in a gas than a liquid.
3
Q
State 3 examples of diffusion.
A
Sugar in coffee. Teabags in hot water. Air freshner being diffused with the air.
4
Q
Do particles diffuse faster in hot or cold water? Why?
A
Hot. Because in hot water, particles will have more kinetic energy, (and therefore move faster) and therefore they diffuse faster in hot water than in cold.
