What is the natural tendency of molecules to spread evenly through a room?
Diffusion
Describe the difference between diffusion and osmosis?
although both are the movement of particles from an area of high concentration to low, diffusion is the movement of many kinds of substances however osmosis refers to the diffusion of water particles only from an area of high water concentration to an area of low water concentration.
What is the difference between bulk motion and diffusion?
The difference between the two is that bulk motion is the flow through the capillary. Diffusion is the movement of the molecules in a fluid.Ê
Why do scientists use two separate terms to describe diffusion and osmosis?
Diffusion describes dispersion of a contaminant through a bulk fluid. Osmosis describes dispersion of a contaminant through a membrane or divider of some sort.
Diffusion and facilitated diffusion?
Diffusion:Diffusion describes the spread of particles through random motion from regions of higher concentration to regions of lower concentration. The time dependence of the statistical distribution in space is given by the diffusion equation. The concept of diffusion is tied to that of mass transfer driven by a concentration gradient, but diffusion can still occur when there is no concentration gradient (but there will be no net flux). diffusion is invoked in the social sciences to describe the spread of ideas.Facilitated diffusion:Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is a process of passive transport, facilitated by integral proteins. Facilitated diffusion is the spontaneous passage of molecules or ions across a biological membrane passing through specific transmembrane integral proteins. The facilitated diffusion may occur either across biological membranes or through aqueous compartments of an organism
What single characteristic of the semipermeable membrane used in the laboratory determines the substances that can pass through them?
The molecular size of the substances is the single characteristic that determines which substances can pass through a semipermeable membrane in the laboratory. Smaller molecules can pass through while larger molecules are blocked.
What is the natural spreading particles through liquids and gases called?
Diffusion
Why diffusion is maximum in gases?
Diffusion is maximum in gases because gas molecules are not closely packed together like in liquids or solids. This allows gas molecules to move more freely and quickly, leading to faster diffusion rates compared to liquids or solids. Additionally, gas molecules have higher kinetic energy, allowing them to move more rapidly and spread out more easily through a medium.
Do solids and liquids diffuse at the same rate?
No. The particles in the solids have different mass as the particles in the liqiuds, so they diffuse at the different rate. but if their particles have the same rate, they will diffuse at the same rate.
What are 5 factors that affect diffusion?
Concentration gradient: The greater the difference in concentration between two areas, the faster diffusion occurs. Temperature: Higher temperatures generally increase the kinetic energy of particles, leading to faster diffusion. Molecular size: Smaller molecules diffuse more quickly than larger ones, as they can move more easily through spaces. Medium through which diffusion occurs: Diffusion occurs more readily in gases and liquids compared to solids. Surface area: The larger the surface area available for diffusion, the faster the rate of diffusion.
What is the dispersion of 2 liquids?
The dispersion of two liquids refers to the mixing or spreading out of the components of the liquids evenly throughout the mixture. This can occur through diffusion, turbulence, or other mixing processes. The degree of dispersion can vary depending on factors such as the viscosity of the liquids, their density, and the method of mixing.
Why do you think diffusion of ions through these channels is generally a slower process than diffusion through the lipid bilayer?
Nope. It Is diffusion
How does matter transport in different media?
Matter transports in different media through various mechanisms, primarily including diffusion, convection, and conduction. In gases, diffusion predominates as molecules move from areas of high concentration to low concentration. In liquids, convection can enhance transport through bulk movement, while diffusion still plays a significant role. In solids, conduction is the primary mode of transport, with energy transferred through atomic or molecular vibrations.
Why is the rate of diffusion of gases more rapid than that of liquids?
Gases diffuse faster than liquids because the intermolecular forces holding gases together are significantly weaker than those holding liquids together. This allows the molecules of the gas to move faster than those of a liquid.
What is relocation diffusion?
The spread of an idea through physical movement of people from one place to another.
Can the intermixing of two solids be termed diffusion?
No, the intermixing of two solids cannot be termed diffusion in the classical sense, as diffusion specifically refers to the movement of particles from an area of higher concentration to one of lower concentration, typically in liquids or gases. In solids, the movement of atoms or molecules is much more restricted and occurs primarily through mechanisms like vacancy diffusion or grain boundary diffusion. While some degree of intermingling can occur in solids under certain conditions, such as high temperatures, it does not align with the traditional definition of diffusion.
What is contagious diffusion?
Contagious diffusion is the spread of an idea, behavior, or characteristic from one person or place to another through direct contact or proximity. It typically occurs rapidly and can spread widely within a population.
