Why does passive diffusion occur?
Passive diffusion occurs because molecules move from an area of higher concentration to an area of lower concentration, in order to reach equilibrium. This process does not require the input of energy.
What is the movement of materials from a higher to a lower concentration?
The movement of materials from a higher concentration to a lower concentration is called diffusion. This process occurs spontaneously to reach equilibrium, where the concentration of the substance is the same throughout the system.
Where to where do particles move during diffusion?
Particles move from an area of higher concentration to an area of lower concentration during diffusion in order to reach equilibrium. This process continues until the concentration of particles is the same throughout the system.
How would describe the relationship between concentration of dye and the rate of diffusion?
The rate of diffusion is directly proportional to the concentration of dye. Higher concentration gradients result in faster diffusion rates, as molecules move from areas of high concentration to low concentration in an attempt to reach equilibrium.
What is a tendency of a molecule to spread into available space to reach equilibrium?
The tendency of a molecule to spread into available space to reach equilibrium is known as diffusion. This process occurs due to the random motion of molecules, leading them to move from areas of higher concentration to areas of lower concentration until a uniform distribution is achieved. Diffusion is driven by the principle of entropy, as systems naturally progress towards a state of maximum disorder.
What is the overall goal of osmosis and diffusion?
To reach an equilibrium
Diffusion stops when molecules reach the?
When molecules reach equilibrium, diffusion stops. This occurs when there is an equal concentration of molecules on both sides of the membrane and no net movement.
How is equilibrium related to diffusion and osmosis?
Equilibrium in diffusion and osmosis is reached when there is a balanced distribution of particles or solutes across a membrane, resulting in no net movement of particles. In diffusion, equilibrium is reached when there is an equal concentration of particles on both sides of the membrane. In osmosis, equilibrium is reached when the water concentration is the same on both sides of the membrane.
List one way osmosis is the same as diffusion?
A substance is passing through a membrane across a concentration gradient to the point of equilibrium.
Why does passive diffusion occur?
Passive diffusion occurs because molecules move from an area of higher concentration to an area of lower concentration, in order to reach equilibrium. This process does not require the input of energy.
How does diffusion take place?
Molecules move from an area from where there is a high concentration to an area where there is a low concentration. This occurs until equilibrium is reach. After equilibrium is reached, diffusion still occurs. (but in "equal trade") Diffusion is caused by the random movements of molecules.
What is the passive movement of gases called?
The passive movement of gases is called diffusion. It is the process by which gases move from an area of high concentration to an area of low concentration in order to reach equilibrium.
What is the movement of materials from a higher to a lower concentration?
The movement of materials from a higher concentration to a lower concentration is called diffusion. This process occurs spontaneously to reach equilibrium, where the concentration of the substance is the same throughout the system.
The ultimate goal of both diffusion and osmosis is?
The ultimate goal of both diffusion and osmosis is to reach a state of balance.
Does diffusion ever stop?
Diffusion will continue as long as there is a concentration gradient present. Once equilibrium is reached and the concentrations are equal throughout, diffusion will stop.
When does diffusion end?
When an equilibrium has been met.
Is equilibrium part of osmosis or diffusion?
yes
