What is diffusion and how do substances move during diffusion?
They move in a bunch mixed together to form or create a substance stronger or sometimes more lethal in a way that is an example of cultural diffusion or chemical diffusion
What does NOT influence the rate of diffusion of a chemical across a plasma membrane?
Besides the concentration of the chemical, the pore size of the plasma membrane, and the osmotic pressure of the cytoplasm - nothing else influences the rate of diffusion of a chemical across a plasma membrane.
What are the major causes of diffusion?
In a chemical sense diffusion is a result of the energy of the system (temperature). The movement of the molecules (or atoms) allow them to disperse themselves amongst like sized particles. Diffusion is a slow process compared to convection - in other words dye spreads slowly through still water, quickly through stirred water. Diffusion is one of the major component of entropy a major component of thermo-dynamics.
What is one specific form of simple diffusion?
There's facilitated diffusion, where proteins channel in molcules; then there's active transport where the cell uses energy to bring in molecules that are to large or a different chemical configuration.
How does the pressure of affect the rate of diffusion?
The higher the pressure, the more easily a chemical diffuses. And seeing as pressure and temperature are directly related, the higher the temperature the more easily a chemical diffuses, and vice versa. This is caused by everything "wanting" to be equal, if there is a higher pressure, then it will diffuse to an area of lower pressure.
How does the impulse jump the synapse?
Chemical diffusion

Is diffusion a physical or chemical change?
Diffusion is a physical change because it only involves the movement of particles from an area of high concentration to low concentration without any change in the chemical makeup of the substances involved.
What carrier molecules are involved in the process of what type of diffusion?
Carrier molecules are not involved.Different between chemical potential leads the diffusion

Are substances broken down during the diffusion process?
Diffusion refers to the moving of a solute from an area of high concentration to an area of low concentration. No chemical reactions take place BECAUSE of diffusion. It is possible that something could be diffusing WHILE undergoing a chemical reaction, but the processes would be unrelated.
Is diffusion a chemical reaction or a change of state?
Diffusion is a change of state. A good example of diffusion is when you can smell something cooking that is in another room. Moisture in the food evaaporates and the gas formed is diffused and you can smell it. I'm not sure that I'm right but i learnt about diffusion in science recently ;-)
Is rust diffusion?
In chemistry diffusion is the passage of particles across a membrane. Diffusion does not relate to the rusting of iron (Fe). Rust itself is an oxidation reaction, rather than diffusion. Oxidation involves the chemical reaction of Fe to atmospheric oxygen (O) to form iron oxides (FeO)s.
Is diffusion a chemical reaction?
Diffusion is the flow of a compound from an area of higher to lower concentration. In a cell water freely diffuses in and out of the cell dependent on the concentration of solutes while larger charged ions and other chemicals have specific channels and carriers. Changing concentration is a chemical change.
