#1
Front (Question)
What is diffusion
Back (Answer)
Diffusion is the spreading out of particles of any substance, in solution or a gas. Resulting in a net movement from an area of higher concentration to an area of lower concentration, down a concentration gradient
#2
Front (Question)
What factors affect diffusion
Back (Answer)
Difference in concentrations, temperature, and available surface area
#3
Front (Question)
Explain why diffusion takes place faster when there is an increase in temperature
Back (Answer)
Heating makes particles move more quickly speeding up diffusion as particles collide more often and harder and spread out faster
#4
Front (Question)
Describe the concentration gradient
Back (Answer)
The difference between high concentration and low concentration. Diffusion occurs down a concentration gradient
