∙ 9y agoThe rate of diffusion depends on the molecular weight of a substance. Smaller and lighter molecules diffuse faster than larger and heavier ones.

∙ 13y agodiffusion rate and molecular weight are inversely relating--the larger the weight, the slower the diffusion rate; and the smaller the weight, the faster the diffusion rate

What process is driven by molecular energy?
diffusion, simple
How does molecular size affect diffusion rate?
Rate of diffusion is indirectly proportional to the molecular mass. This means that for a heavier particle, (i.e, higher molecular mass), the rate of diffusion is slower because they would have to travel the same distance with more energy compared to smaller molecules. Imagine a fat man trying to run and a slimmer man, the fat man would require more energy.Read more: What_is_the_relationship_between_the_rate_of_diffusion_and_the_molecular_mass_of_a_substance
The movement of particles from a high concentration to a low concentration?
diffusion
What motion is the net movement of particles of a substance from areas of high concentration to areas of low concentration?
This is diffusion. No energy required, molecules do this just based on random molecular motion. Example: a drop of ink dropped into a beaker of water will "diffuse" until it is as spread out as possible.
How diffusion and osmosis limit the size of a cell?
becauuse it does
Does diffusion effect cell size?
Yes
What is the effect of size of uptake on diffusion in agar?
larger the size, the smaller the surface area to volume ratio, hence the slower the rate of diffusion into the agar jelly :)
What conditions affect diffusion?
Factors that may affect Diffusion rates are: Temperature, Concentration, Different tissue types, Molecular size, Surface area to volume ratio.
What is the process when a substance is spread through a gas?
Diffusion (technically molecular diffusion)
What is the scientific term for diffusion?
molecular diffusion spreading more when in a larger area
What is driven by molecular energy?
diffusion, simple
Which process can be explained by the kinetic-molecular theory?
Diffusion can be explained by the kinetic-molecular theory.
Why does the molecular size of an individual gas particle have no effect on the total volume of the gas?
gasses take up the entire volume of their containers regardless of their molecular size. The intermolecular space is so huge that their molecular mass is negligible in comparison.
What process is driven by molecular energy?
diffusion, simple
What factor affects the rate of diffusion?
Diffusion refers to the process where substances from a highly concentrated area move to a place with a lower concentration. The three factors that affect the rate of diffusion are temperature, concentration gradient and the molecular weight of the substances.
How do thing move through the cytoplasm?
Diffusion and molecular pumps
What is the random mixing of gas called?
This phenomenon is the molecular diffusion.
