What is meant by the net movement of particles?
net movement of particles mean the spreading out or over all movement of particles
Why is the term 'net movement' used in diffusion instead of 'movement'?
If you open an account and deposit $100 in a bank, then withdraw $60 the following day, the result of all this high finance is a balance of $40 in your account.You could say that some money has moved into the bank, some out, but on balance the movement was inward. That movement is net movement.Net movement = (movement in one direction) - (movement in the opposite direction)It is much the same with diffusion, whether in and out of a cell or anywhere else.All atoms, ions, and molecules are continually on the move. (The higher the temperature, the faster they zip about.) But they are moving randomly in all directions.The reason diffusion occurs is that the atoms are more crowded in one place (there is a higher concentration there). By random movement and rebounds from collisions, inevitably the atoms become more evenly dispersed about the available space.During the time that the concentrations in different places are evening up, there is on balance a flow away from the region of higher concentration. But on balance. Some atoms are going the other way, like people battling to get into a city in the late afternoon against the homeward-bound commuters.
Do particles continue to move when equilibrium is reached?
In a system at equilibrium, the overall movement of particles may appear to be stationary, but individual particles continue to move randomly due to their thermal energy. This continuous motion at the molecular level is known as thermal motion.
What is diffusion simple?
Simple diffusion is the net movement of substances from a region of high concentration to a region of low concentration so its overall net movement is along the concentration gradient. Simple diffusion does not require energy therefore it is 'passive', substances are diffused across the membrane between the phospholipids.
What would happen to a cell in an isotonic solution?
In an isotonic solution, the concentration of solutes outside the cell is equal to the concentration of solutes inside the cell. As a result, there is no net movement of water, and the cell maintains its normal shape and size.
Is dynamic equilibrium the result of diffusion where is continuous movement of particles in and out of a cell true?
Yes, dynamic equilibrium in the context of a cell refers to a state where there is continuous movement of particles across the cell membrane, resulting in no net change in concentration. This occurs due to diffusion, where particles move from areas of higher concentration to areas of lower concentration. While individual particles are constantly moving in and out, the overall concentrations remain stable, indicating a balance or equilibrium.
What is the difference between effusion and diffusion in chemistry?
Effusion and diffusion are both processes by which particles move from an area of high concentration to an area of low concentration. The key difference is that effusion specifically refers to the movement of gas particles through a small opening, while diffusion is the overall movement of particles in a substance.
What do you learn with diffusion?
Diffusion is the process by which molecules spread out from an area of higher concentration to an area of lower concentration. By studying diffusion, you can learn about the movement of particles in a substance and how this affects the overall distribution of these particles. Diffusion is important in various biological processes, such as the exchange of gases in the lungs and the movement of nutrients within cells.
How does energy from vibrations in matter contribute to the overall movement and behavior of particles in a system?
Energy from vibrations in matter contributes to the overall movement and behavior of particles in a system by transferring kinetic energy. When matter vibrates, it creates energy that can be transferred to nearby particles, causing them to move and interact with each other. This movement and interaction of particles ultimately determine the overall behavior and dynamics of the system.
What is the difference between dilution and diffusion?
Dilution involves adding a solvent to reduce the concentration of a solute in a solution. Diffusion is the process by which molecules move from an area of high concentration to an area of low concentration to reach equilibrium. Dilution affects the overall concentration of a solution, while diffusion is the movement of particles within a solution.
Defusion and osmosis?
Diffusion is when there is lower concentration in one area than another so the particles that are in the area with higher concentration move to the area with lower concentration to make the concentration same in both areas. Osmosis is a type of diffusion but diffusion that only has water involved. So if there's no water... it's not osmosis. It's gotta be diffusion.
What happens to a particle in diffusion?
When particles diffuse they break apart, down into simpler substances. Diffusion is the net movement of molecules from high to low concentration through random motion. From the particle point of view it just moves about at random (as usual) but the overall effect is for the particles to spread out evenly.
How does temperature affect the speed of movement of particles?
Temperature affects the speed of movement of particles by increasing their kinetic energy. As temperature rises, particles move faster and collide more frequently, leading to an increase in their overall speed.
Do the movement of particles increase or decrease during condensation?
The movement of particles decreases during condensation. As a substance changes from a gas to a liquid during condensation, the particles come closer together and lose some of their kinetic energy, resulting in a slower overall movement.
How does thermodynamics apply to diffusion?
The higher the thermal energy of a diffused sample AND its solute, the faster the kinetic rate of motion of the dissolved particles, or atoms, and the faster their rate of diffusion throughout the solute.
How the size of particle effect osmotic pressure?
The size of particles does not directly affect osmotic pressure. Osmotic pressure is primarily influenced by the concentration of particles in a solution rather than the size of the individual particles. Larger particles may contribute more to the overall concentration, which could indirectly impact osmotic pressure.
when does the net movement of osmosis and diffusion stop?
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.
