Why is diffusion affected by a decrease in concentrated gradient?
Diffusion is affected by a decrease in concentration gradient because concentration gradient is directly proportional to the rate of diffusion. A decrease in concentration gradient also lowers the rate of diffusion.
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
Effect of molecular size on diffusion?
Molecular Diffusion Of Light
Does a temperature increase increase the rate of diffusion?
yes the higher the temprature the quicker the rate of diffusion
How shape affect the rate of diffusion?
diffusion, its annoying :) m.kk
Diffusion at high temperatures?
According to Hook's Law: Rate of Diffusion is directly proportional to (Conc. Gradient x Temperature) / Diffusion distance
How does surface area to volume ratio of a cell affect rate of diffusion?
The surface area to volume ratio of a cell affects the rate of diffusion in that the higher the ratio, the faster the rate of diffusion. This is a directly proportional relationship.
Why is diffusion affected by a decrease in concentrated gradient?
Diffusion is affected by a decrease in concentration gradient because concentration gradient is directly proportional to the rate of diffusion. A decrease in concentration gradient also lowers the rate of diffusion.
What is the diffence in rate of diffusion hot and cold water?
Diffusion is a process which is affected by changes in temperature in the system where it is taking place. When the temperature is high, the rate of diffusion is high and when the temperature is low, the rate of diffusion is less.Hence, we can say that diffusion is directly proportional to temperature.Therefore, the answer to your question is that diffusion will be high in hot water and in cold water, it will be slow.
How does temperature effect diffusion rates?
Temperature and diffusion rates are usually linearly proportional. As temperature increases diffusion rate also increases and vice versa. In most cases, diffusion rate will reach 0 after saturation or the maximum possible temperature.
What is the definition of Graham's law of diffusion?
This law relates the rate at which a gas diffuses or effuses to the type of molecule in the gas. This rate of diffusion of a gas is inversely proportional to the square root of it's molecular mass.
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.

What scientific conclusion did thomas graham make?
The law of diffusion. It states that " at constant temperature, the rate of diffusion of any gas is inversely proportional to the square root of its density".
State the Graham's law?
graham's law of diffusion states that the rate of diffusion of a gas is inversely proportional to the square root of its density provided the temperature and pressure remain constant
Why is a large surface area necessary for the alveoli in the lungs?
According to fick's law rate of diffusion =(proportional to)= Surface area x Diffusion gradient Diffusion Pathway thickness So for a sufficient rate of diffusion, Surface area must be large The diffusion pathway is already at it's minimun of 1 cell thick and the gradient is harder to adjust. There are around 600 million alveoli in the lungs that have a cummulitive surface area of around 70m2.
What happens to rate of diffusion on heating?
On heating the rate of Diffusion increases..
What is the effect of the density of liquid on the rate of diffusion?
The increase in density will decrease the rate of diffusion. There is an inverse relation between density and rate of diffusion.
