Moving from an area of high concentration to an area of low concentration(across a concentration gradient) to create equilibrium on both sides.

Is water freezing into ice an example of diffusion?
These are two different processes. Diffusion is when two substance mix together, evaporation is when a liquid turns into a gas. If diffusion where to effect evaporation it would be to do with changing the properties of the liquid being evaporated.
Describe 2 properties of an exchange surface that would facilitate rapid diffusion rates?
Large surface area: A greater surface area allows for more molecules to come into contact with the surface, increasing the rate of diffusion. Thin membrane: A thin exchange surface reduces the distance that molecules have to travel to diffuse across the surface, speeding up the diffusion process.
What is substitutional diffusion?
Substitutional diffusion is a type of diffusion mechanism where atoms of one type replace atoms of a different type within a material's crystal lattice. This process occurs when atoms are able to move freely across the lattice sites. Substitutional diffusion can lead to changes in material properties and structure over time.
What is diffusion annealing?
Diffusion annealing is a heat treatment process that involves heating a material to a specific temperature and holding it there for a period of time to allow for the diffusion of atoms within the material. This process helps to reduce internal stresses, improve the material's homogeneity, and enhance its mechanical properties.
What causes diffusion to start and stop?
Diffusion begins when there is a concentration gradient, meaning particles move from an area of higher concentration to an area of lower concentration to achieve equilibrium. The process continues until the concentrations become equal, at which point diffusion effectively stops as there is no longer a gradient to drive the movement of particles. Factors such as temperature, pressure, and the properties of the medium can influence the rate of diffusion.
What properties of water that help plants transpire?
Evaporation and diffusion
Why do you have to learn about diffusion and osmosis?
These are scientific properties . It is necessary to learn these properties to gain a better understanding of science , and how the world works .

What are the properties of land?
Liquids does not have a definite shape, but have a definite volume. Diffusion is a slow process and liquids are compressible.

What is the graph of diffusion vs temperature?
The graph of diffusion vs temperature typically shows an increase in diffusion rate with increasing temperature. This is because higher temperatures increase the kinetic energy of particles, leading to faster movement and more frequent collisions, which in turn promotes faster diffusion. However, extreme temperatures can also denature proteins or change the properties of the medium, affecting diffusion rates.
When two gases are mixed what is it called?
When two gases are mixed together, it is referred to as a gas mixture. This is because the gases are physically combined, retaining their individual properties without a chemical reaction taking place.
Does diffusion ever endand why?
No, never.After a time saturation occurs,so no change in properties are observed.But still diffusion going on. Also liquid have a week intermolecular force causing internal motion every time(+ entropy).
What does exponential apparent diffusion?
Exponential apparent diffusion refers to a mathematical model used in diffusion studies, particularly in medical imaging like MRI. It describes how the apparent diffusion coefficient (ADC) of water molecules in tissues changes over time, often exhibiting an exponential decay pattern. This concept helps in understanding tissue characteristics and can be useful in diagnosing conditions such as tumors or stroke by analyzing the diffusion properties of water in different environments.
