Diffusion Experiment Flashcards
Natural movement of molecules from region of higher concentration to lower concentration
Diffusion
Diffusion is propelled by
Random Motion of Particles
process which continue until equilibrium is achieved, where concentration of molecules becomes equal across the system
Diffusion
Does not require energy input from the cell or organism
passive process
Factors Affecting Diffusion
Concentration gradient
Temperature
Molecular Size and Mass
Surface Area
The greater the difference in ___ between two region, the faster the rate of diffusion
Concentration Gradient
Concentration
Higher__ generally increases kinetic energy of molecules causing to move rapidly and increase rate of diffusion
Temperature
___ &___ molecules diffuse more than ___&___ ones.
Molecular size and mass
Smaller and lighter
Larger and Heavier
it has higher average speed and less hindered by collision with other molecules
Smaller molecules
_____ increases the rate of diffusion since it provides more space for molecules to move across
Surface area
Larger surface area
Objective of the experiment
To measure how fast each dye diffuses in various water temperature
To demonstrate the rs between temp and rate of diffusiom
Diffusion process is in between
Diffuses in moderate pace
Normal water
Diffuses slower as collision of molecules slow down
Cold Water
Diffuses faster as collision of molecules fasten
Hot Water
Importance of Diffusion
Gaseous Exchange during Respiration
Removing Waste Products
Process of Photosynthesisi in Plants
