Define term gradient give definition of fick's law?
Gradient refers to the rate of change of a variable over a specific distance or direction. Fick's Law is a mathematical equation that describes the flux of a substance through a medium, considering the concentration gradient of the substance and the permeability of the medium. It is commonly used in fields like chemistry and biology to determine the rate of diffusion of molecules.
What is apparent diffusion coefficient?
The apparent diffusion coefficient (ADC) is a quantitative measure that reflects the diffusion of water molecules in tissues, commonly used in diffusion-weighted magnetic resonance imaging (DWI). It provides information about tissue microstructure and cellularity by measuring how freely water molecules move within cells and extracellular space. Changes in ADC values can indicate conditions such as inflammation, ischemia, or tumor growth.
Is passive diffusion a spontaneous process?
Yes, passive diffusion is a spontaneous process.
How does the state of matter affect diffusion?
The state of matter affects diffusion rate by changing the spacing between particles. In gases, particles are spread out more, allowing for faster diffusion. In liquids, particles are closer together, slowing down diffusion. In solids, diffusion is minimal due to the fixed position of particles.
What is the equation for deriving Fick's first law and how is it used to describe the diffusion of particles in a system?
Fick's first law equation is: J -D(dC/dx), where J is the flux of particles, D is the diffusion coefficient, C is the concentration of particles, and x is the distance. This equation describes how particles diffuse in a system by showing how the flux of particles changes with concentration gradient. It helps us understand how particles move from areas of high concentration to low concentration in a system.
Why you take square root in grahams law of diffusion?
for simplicity
What is grahams law of diffusion?
graham's law of diffusion states that the rates of which gases diffuse at the same temperature are inversely proportional to the square roots of their densities.
What is the definition of diffusion current?
Diffusion current is current that is generated due to the vibration of electrons.
Which is better fruity pebbles or golden grahams?
Golden Grahams of course! Golden Grahams of course!
What is the definition of contagious diffusion?
Contagious diffusion is a branch of expansion diffusion. It refers to a cultural trait spreading across a population like a disease.
When was Teddy Grahams created?
Teddy Grahams was created in 1988.
When was S'mores Grahams created?
S'mores Grahams was created in 1982.
Is there algebra behind Graham's law?
Algebra can be used to solve for an unknown value in Graham's Law formula. The Grahams law formula can use algebra for solving for an unknown value in the formula.
What is the definition for diffusion?
Diffusion is one type of passive transport. In Diffusion, molecules move from a higher concentration gradient to a lower concentration gradient. Diffustion does NOT need energy, or ATP.Q: What is the DEFINITION of DIFFUSION?A: Diffusion- a type of passive transport in cells in which molecules move from areas where there are more of them to areas there are fewer of them.ur wlcm (: SnazzyChazzy
Who Developed law of diffusion?
Graham!
When was Grahams Hi-Fi created?
Grahams Hi-Fi was created in 1929.
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
