What is diffusion in science terms?
In biology, diffusion is the passive movement of molecules or particles along a concentration gradient, or from regions of higher to regions of lower concentration. Diffusion is the free movement of particles in a liquid or gas down a concentration gradient.
What is the definition of diffusion in scientific terms?
Diffusion refers to the process by which molecules intermingle as a result of their Kineti energy of random motion
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.
What is solid in terms of arrangement of particles?
Anything that has particles that are closely packed together. Examples: * A cup * A bowl * A lightbulb * A faucet * A microwave * A shirt
Which terms best describes the rate of movement of carbon between reservoirs?
constant
How does the process of diffusion differ from convection in terms of the movement of particles?
Diffusion involves the movement of particles from an area of high concentration to an area of low concentration, while convection involves the transfer of heat through the movement of a fluid. In diffusion, particles move randomly, while in convection, particles move in a specific direction due to the flow of the fluid.

What are the differences between diffusion and convection in terms of the movement of particles in a fluid medium?
Diffusion is the movement of particles from an area of high concentration to an area of low concentration, while convection involves the transfer of heat through the movement of the fluid itself. In diffusion, particles move randomly, while in convection, the fluid moves in a specific direction due to temperature differences.
What is the difference between osmosis and diffusion in terms of solute and solvent?
Osmosis is the spontaneous net movement of water across a semipermeable membrane from a region of low solute concentration to a solution with a high solute concentration, down a solute concentration gradient. Diffusion is a spontaneous movement of particles from an area of high concentration to an area of low concentration. (ex. tea flavoring moving from an area of high to low concentration in hot water.)
What is the difference between diffusion and bulk flow in terms of the movement of substances across a membrane?
Diffusion is the movement of substances from an area of high concentration to low concentration, while bulk flow is the movement of substances in a fluid due to pressure differences. Diffusion occurs passively, while bulk flow requires energy.
What are the differences between convection and diffusion in terms of their mechanisms of heat transfer?
Convection involves the transfer of heat through the movement of fluids, such as air or water, while diffusion involves the movement of heat from areas of high concentration to areas of low concentration without the need for fluid movement.
What is the difference between diffusion and facilitated diffusion in terms of the movement of molecules across a cell membrane?
Diffusion is the movement of molecules across a cell membrane from an area of high concentration to low concentration without the need for a protein. Facilitated diffusion also moves molecules from high to low concentration, but requires a specific protein to help them pass through the membrane.
The movement of molecules from high concentration to low concetration?
This process is called diffusion. It occurs when molecules move randomly and eventually spread out to areas of lower concentration to achieve an equilibrium. Diffusion is a passive process, meaning it does not require energy input.
What is the definition of diffiusion in science terms?
Diffusion is the process where molecules or particles move from an area of higher concentration to an area of lower concentration, resulting in the equal distribution of the substances. It plays a crucial role in various biological and physical processes, such as the exchange of gases in the lungs and the movement of nutrients into cells.
How is facilitated diffusion different from regular diffusion in terms of the mechanism of transport?
Facilitated diffusion is different from regular diffusion because it involves the use of transport proteins to help molecules move across the cell membrane, while regular diffusion does not require any proteins and relies on the natural movement of molecules from an area of high concentration to low concentration.
What is diffusion and how does it occur?
Diffusion is the movement and spreading of substance throughout its location. For example if you spray perfume on one side of the room the scent will spread throughout the entire room. Mass transfer is similar because its the movement of particles from areas of high concentration to areas of lower concentration. Going back to our perfume example, there was a high concentration of perfume particles where you sprayed the perfume and a low concentration on the other side of the room, the molecules moved from the area with a high concentration to the area with a lower concentration.
What is the difference between facilitated diffusion and simple diffusion in terms of the mechanisms by which molecules move across a cell membrane?
Facilitated diffusion involves the movement of molecules across a cell membrane with the help of specific proteins, while simple diffusion does not require any proteins and relies on the molecules moving freely through the membrane.
