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.

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 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.
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.
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 are smaller than cells but larger than atoms?
Molecules are smaller than cells but larger than atoms. They are composed of atoms bonded together to form a distinct structure.
Does diffusion occur slow or fast?
Diffusion can occur at varying speeds depending on factors such as temperature, concentration gradient, and molecular size. In general, smaller molecules diffuse faster than larger molecules, and higher temperatures typically increase the rate of diffusion.
Does color of dye affect diffusion?
Yes, the color of a dye can affect its diffusion rate. Darker colored dyes tend to have larger molecules and can diffuse more slowly compared to lighter colored dyes with smaller molecules. Additionally, the presence of certain chemical groups in the dye molecules can also influence their diffusion properties.
