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
What process is driven by molecular energy?
The process of diffusion is driven by molecular energy, where molecules move from an area of higher concentration to an area of lower concentration. This process occurs due to the random motion of molecules caused by their kinetic energy.
What is the relationship between molecular size and diffusion rate?
Not exactly, although they can be. If two molecules are both composed of the same elements, the one that has more atoms in it, the one with more atoms will have a larger molecular mass, and a larger molecular size. However, different elements weigh different amounts.Take for example the molecule octane, which is an ingredient in gasoline, with formula C8H18. Octane is relatively large, and has a molecular mass of approximately 114 grams per moles. However, a single atom of the element lead, Pb, is much smaller than the molecule octane, and yet the molar mass of lead is 207.2 grams per mole! So it is much heavier, and yet smaller.On the other hand, hydrogen gas (H2) has a molar mass of 2 grams per mole, and chlorine gas (Cl2) has a molar mass of 71 grams per mole, and Cl2 is indeed much larger than H2.And so you can see that it depends on the composition of the things you are comparing.
What is the speed of diffusion of the purple coloration through the water?
you have to start with the amount of sunlight it is receiving or if it is even getting any other than that it takes about 1 .25 seconds to move through the water
What is diffusion rate proportional to?
rate of diffusion depends on the concentration gradient, surface area, distance over which diffusion takes place, size and nature of the diffusing molecule.
Does diffusion effect cell size?
Yes
What are some factors that might aid or slow diffusion?
Factors that can aid diffusion include high temperature, smaller molecular size, steep concentration gradients, and a larger surface area for exchange. Factors that can slow diffusion include low temperature, larger molecular size, long diffusion distances, and obstacles in the medium through which diffusion is occurring.
What influences the rate of diffusion?
The rate of diffusion is influenced by the concentration gradient, temperature, molecular size, and the medium through which the particles are diffusing. A steeper concentration gradient, higher temperature, smaller molecular size, and a less dense medium all tend to increase the rate of diffusion.
The rate of diffusion depends on?
The rate of diffusion depends on the concentration gradient, temperature, molecular weight, and surface area available for diffusion. A steeper concentration gradient, higher temperature, smaller molecular weight, and larger surface area all contribute to faster rates of diffusion.
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?
Diffusion is affected by factors such as temperature, concentration gradient, molecular weight/size of particles, and the medium through which the particles are diffusing. For example, higher temperatures generally increase the rate of diffusion, while larger particles diffuse more slowly.
What is the scientific term for diffusion?
molecular diffusion spreading more when in a larger area
What is the process when a substance is spread through a gas?
Diffusion (technically molecular diffusion)
What is driven by molecular energy?
diffusion, simple
What can affect the speed of diffusion?
The speed of diffusion can be affected by the temperature, molecular size, concentration gradient, and the medium through which diffusion occurs. Higher temperatures typically increase the speed of diffusion, while larger molecules diffuse more slowly. Additionally, a steeper concentration gradient across the medium will result in faster diffusion.
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 influences diffusion?
Diffusion is a type of passive transport. The factors that influence diffusion include: concentration gradient, size of molecule involved, distance the molecule has to travel, temperature, solubility of the molecule and surface area.
