Diffusion and factors affecting diffusion rate Flashcards
1
Q
What is diffusion?
A
The spreading of one substance through another.
2
Q
Where can diffusion only occur?
A
Through liquids and gases.
3
Q
What does diffusion occur as a result of?
A
The random motion of particles.
4
Q
What does the rate of diffusion increase with?
A
-Increasing temperature.
- Because particles move faster with increased temperature.
5
Q
What is the rate of diffusion greater in?
A
- Substances with lower molar masses.
- Because particles that have a lower molar mass are lighter.
