What Is Example Of Diffusion? Diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. A familiar example is the perfume of a flower that quickly permeates the still air of a room. What are three
What Is One Reason Why Cultural Diffusion Is A Selective Process? What is one reason why cultural diffusion is a selective process? he overt form of a trait may have a different meaning for the second culture. What are 2 examples of cultural diffusion? An example of cultural diffusion with negative effects would be the
What Is The Concept Of Steady State As It Applies To Diffusion? is the change in concentration with respect to change in position. For example, if we have reservoir (1) and reservoir (2) separated by a membrane. Fick’s law describes how concentration changes between two reservoirs, or in the other words between concentration. What is
What Is The Bystander Effect And Diffusion Of Responsibility? Diffusion of responsibility refers to the fact that as the number of bystanders increases, the personal responsibility that an individual bystander feels decreases. … But when the costs of helping and not helping are both high, bystanders feel a strong conflict between the desire to act
What Is The Extent Of A Features Spread Over Space? Key Term: Definition: Concentration The extent of a feature’s spread over space Connections Relationships among people and objects across the barrier of space! Contagious diffusion The rapid, widespread diffusion of a feature or trend throughout a population! What is the arrangement of a feature in
What Is The Formula For Diffusion? Diffusion coefficient is the proportionality factor D in Fick’s law (see Diffusion) by which the mass of a substance dM diffusing in time dt through the surface dF normal to the diffusion direction is proportional to the concentration gradient grad c of this substance: dM = −D grad c
What Is The Main Cause Of Diffusion? The primary cause of diffusion is random motion of atoms and molecules in a substance. What is the ultimate cause of diffusion? Passive transport is a way that small molecules or ions move across the cell membrane without input of energy by the cell. … The difference in
What Is The Process By Which An Object Or An Idea Spreads To Different Cultures? Cultural diffusion refers to the process by which a cultural trait, material, object, idea, or behaviour pattern is spread from one society to another. … introduced new cultural traits. What is the process by which culture is spread? Diffusion, also
What Is The Rule That Governs The Direction Of Diffusion? According to Fick’s laws, the diffusion flux is proportional to the negative gradient of concentrations. It goes from regions of higher concentration to regions of lower concentration. What is the rule of diffusion? Diffusion rule 1. there must be openings in the membrane and the
Is Diffusion Coefficient Dependent On Temperature? The diffusion coefficient is a physical constant dependent on molecule size and other properties of the diffusing substance as well as on temperature and pressure. How does diffusion coefficient change with temperature? The coefficient of diffusion increases gradually as the temperature of the air increases. The activation energy was
