Diffusion

Question 1

What does the particulate theory of matter state?

Answer 1

that matter is made up of tiny particles which can move

Question 2

What is diffusion?

Answer 2

the movement of particles from an area of high concentration to an area of low concentration until the particles are evenly distributed.

Question 3

How does diffusion occur in gases?

Answer 3

like air and liquids because their particles can move around freely

Question 4

Name an example of diffusion in gases?

Answer 4

the use of bromine gas

Question 5

Explain the process of diffusion using bromine gas?

Answer 5

if you place a small amount of liquid bromine in a jar and check it one hour later, the bromine vapor would have diffused and filled the jar

Question 6

Further explanation of diffusion using bromine gas?

Answer 6

The bromine liquid vaporized to produce a reddish, brownish gas. The gas particles then diffused from an area of high concentration (the bottom of the jar) to an area of lower concentration (the top of the jar) until evenly distributed
