Bet movement of a substance will stop when the system reaches equilibrium, meaning the forces acting on the particles are balanced, and there is no net movement. This typically occurs when the concentration of the substance becomes uniform throughout the medium, or when external conditions such as temperature and pressure stabilize. In closed systems, this can happen over time as particles diffuse and distribute evenly.
The water is not moving equilibrium.
Diffusion
A concentration gradient of a substance drives the movement of that substance from an area of high concentration to an area of low concentration. The steeper the concentration gradient, the faster the movement of the substance, requiring less energy to transport it. If the concentration on both sides of the gradient is equal, there is no net movement of the substance.
This process is called diffusion. If the substance moving is water, it is called osmosis.
DIFFUSION DIFFUSION
The water is not moving equilibrium.
DIFFUSION DIFFUSION
A concentration gradient ceases to exist when there is an equal distribution of a substance across a space or membrane. This equal distribution results in no net movement of the substance from one area to another, causing the concentration gradient to reach equilibrium.
The net movement of osmosis stops when the concentration of solute is equal on both sides of the membrane, resulting in equilibrium. At equilibrium, there is no further movement of water molecules across the membrane.
Diffusion
Diffusion
The net movement of osmosis and diffusion stops when the concentration of solute is the same on both sides of the membrane, creating an equilibrium. At this point, there is still movement of molecules back and forth, but there is no overall change in concentration.
No, molecular motion does not stop when diffusion stops. Molecular motion refers to the movement of molecules within a substance, which continues even when there is no net movement of molecules from one region to another (diffusion).
A concentration gradient of a substance drives the movement of that substance from an area of high concentration to an area of low concentration. The steeper the concentration gradient, the faster the movement of the substance, requiring less energy to transport it. If the concentration on both sides of the gradient is equal, there is no net movement of the substance.
When there is no difference in concentration of a substance from one area to another, we refer to this as equilibrium. At equilibrium, there is an equal distribution of the substance, and there is no net movement of the substance in any particular direction.
Active transport or facilitated diffusion could result in the net movement of a substance into a cell if it is more concentrated inside the cell than in the surroundings. In active transport, energy is required to move the substance against its concentration gradient. In facilitated diffusion, specific carrier proteins help the substance move into the cell down its concentration gradient.
