Effect of molecular size on diffusion?
In general, larger molecules diffuse more slowly than smaller molecules because they have a larger molecular weight and therefore experience more resistance from the surrounding medium as they move. This is due to the fact that larger molecules have a lower diffusion coefficient and therefore diffuse at a slower rate. Additionally, larger molecules may also be more prone to interacting with other molecules in their surroundings, further slowing down their diffusion.
How does the size of molecules affect diffusion?
The smaller the molecule, the faster it can diffuse through a medium. Larger molecules have more difficulty moving through the medium due to their size and shape, which slows down the rate of diffusion.
What is the breakdown of large molecules into smaller ones be absorbed by the cells called?
The breakdown of large molecules into smaller ones to be absorbed by cells is called digestion. This process involves the breakdown of carbohydrates, proteins, and fats into their smaller components (such as glucose, amino acids, and fatty acids) that can be readily absorbed and used by the body.
What is the process of breaking larger molecules into smaller molecules called?
The process of breaking larger molecules into smaller molecules is called catabolism. This process typically involves the release of energy as larger molecules are broken down into smaller units that can be used for cellular activities.
Why don't starch molecules pass through partially permeable membranes?
Starch molecules are too large to pass through the pores of a partially permeable membrane. The size exclusion limit of the membrane restricts the passage of larger molecules like starch while allowing smaller molecules like water to pass through via osmosis.
Do all liquids diffuse the same way?
no because different molecules have different sizes. Smaller molecules will diffuse faster than larger molecules.
True or false Gases with high molecular weights diffuse more slowly than gases with lower molecular weights?
True. Gases with high molecular weights have slower diffusion rates compared to gases with lower molecular weights due to their larger mass and lower average speed of the molecules.

Does the insulin can through pass the dialysis tube?
Insulin molecules are relatively small and can pass through dialysis tubing, which typically has a molecular weight cutoff that allows small solutes to diffuse through while retaining larger molecules. Therefore, insulin can diffuse through the dialysis tube during the dialysis process. This property is utilized in dialysis to separate smaller waste products from larger molecules in blood.
Does having a mixture of molecules effect their ability to diffuse?
Yes, having a mixture of molecules can affect their ability to diffuse. The size, charge, and polarity of the molecules can influence how quickly they move through a medium, as larger or more polar molecules may diffuse more slowly than smaller or nonpolar ones. Additionally, interactions between different molecules in a mixture can create barriers or alter the diffusion pathway, further affecting the overall diffusion rate. Therefore, the composition and characteristics of the mixture play a significant role in diffusion dynamics.

Does hydrogen diffuse faster than methane?
Yes, hydrogen diffuses faster than methane. The hydrogen molecule, H2, is the smallest of all molecules and it is considerably smaller than the methane molecule, CH4. Smaller molecules move faster, and therefore diffuse faster, at any given temperature, than larger molecules.
Do larger molecules have stronger intermolecular forces compared to smaller molecules?
Yes, larger molecules generally have stronger intermolecular forces compared to smaller molecules due to increased surface area and more opportunities for interactions between molecules.
Does chloride diffuse out of a dialysis bag?
Yes, chloride ions can diffuse out of a dialysis bag if the dialysis membrane is permeable to them and if there is a concentration gradient. Dialysis works by allowing smaller molecules and ions to pass through the membrane while retaining larger molecules. If the concentration of chloride outside the bag is lower than inside, chloride will move out of the bag to equalize the concentrations.
Infer the relationship between rate diffusion and molecular mass of a substance?
The rate of diffusion is inversely proportional to the molecular mass of a substance. Generally, smaller molecules diffuse faster than larger ones because they are able to move more easily through a medium due to their lighter weight. Conversely, larger molecules diffuse slower because they collide more frequently with other molecules and require more energy to move.
What process will combine smaller molecules together to create a larger one?
Polymerization is the process of combining smaller molecules (monomers) together to form larger molecules (polymers). This can be achieved through various methods such as condensation polymerization or addition polymerization.
