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.
A cell that is 35 percent water is placed in a solution that is 35 percent water Which way will the net movement of water go?
If the cell and the solution contain the same percentage of water, the solution is isotonic. This means that the net movement of water will not be in either direction, there will be no net movement.
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.
Why is there an overall movement of particles in the cell?
The overall movement of particles in a cell is primarily driven by processes such as diffusion, osmosis, and active transport. Diffusion allows particles to move from areas of higher concentration to lower concentration, facilitating the distribution of nutrients and waste removal. Osmosis specifically pertains to the movement of water across semipermeable membranes, maintaining cellular balance. Active transport, on the other hand, uses energy to move particles against their concentration gradient, ensuring that essential substances are available within the cell.
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.
Why is there an overall movement of particles in the human cell?
The overall movement of particles in human cells is driven by various processes, including diffusion, active transport, and cytoplasmic streaming. Diffusion allows molecules to move from areas of high concentration to low concentration, while active transport utilizes energy (ATP) to move substances against their concentration gradient. Additionally, the cytoskeleton facilitates the movement of organelles and vesicles within the cell, ensuring proper distribution and function of cellular components. This dynamic movement is essential for maintaining homeostasis, signaling, and overall cellular function.
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 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 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.
