Diffusion Flashcards
What is Diffusion?
The movement of a substance from an area of high concentration to an area of lower concentration
How does diffusion spread?
Through the air and how concentrated liquids spread out when placed in water
What does diffusion occur in?
In liquids and gases when their particles collide randomly and spread out
What affects Diffusion?
The type of substance and Temperature
What is the type of substance?
This is when substances diffuse more quickly through gases than through liquids
Why is this a type of substance?
Because the particles in a gas are more spread out and move faster than the particles in a liquid
What is the temperature that affects Diffusion?
The hotter the gas or liquid, the faster diffusion happens
Why does temperature affect Diffusion?
Because the particles have more energy and move faster at higher temperatures
