Just about the only very, very large area in our Universe where the above conditions could be met is Interstellar Space, as long as the masses of gas and the clouds of dust can be avoided.
If Space is defined as all of the water in Earth's Oceans, within given layers molecular concentrations are relatively constant.
What else can I help you with?
What process is the movement of molecules down a concentration gradient until equilibrium is reached?
The movement of molecules down a concentration gradient until equilibrium is reached is called diffusion. This process occurs when molecules naturally move from an area of higher concentration to an area of lower concentration, driven by their kinetic energy. Diffusion continues until the concentration of molecules is uniform throughout the space, achieving equilibrium where there is no net movement of molecules in any direction.
What process causes gasses to move along a test tube?
Gas molecules move along a test tube due to diffusion, which is the random movement of molecules from an area of high concentration to an area of low concentration. This process allows the gas molecules to spread out evenly in the available space within the test tube.
What happens in a cell transportation lab report?
When a cell membrane is said to be selectively permeable, it means that the cell membrane controls what substances pass in and out through the membrane. This characteristic of cell membranes plays a great role in passive transport. Passive transport is the movement of substances across the cell membrane without any input of energy by the cell. The energy for passive transport comes entirely from kinetic energy that the molecules have. The simplest type of passive transport is diffusion, which is the movement of molecules from an area of high concentration to an area of lower concentration. Diffusion moves down the concentration gradient, which is the difference in the concentration of molecules across a space. Osmosis is a type of diffusion in which water molecules move down the concentration gradient. When the concentration of solute molecules outside the cell is lower than the concentration of solute in the cytosol , the solution outside is hypotonic to the cytosol. If the concentration of solute molecules is higher outside of the cell, the solution outside is said to be hypertonic. The solution outside is isotonic if the concentration is equal on both sides of the cell membrane.
Why cant big molecules pass through wall guts?
The cell walls of the intestinal cells do not allow the passage of large molecules through them; in addition, the tight junctions between the cells blocks the transfer of large molecules through the interstitial space.
What are factors on which rate of diffusion depends?
Diffusion depends on where the higher and lower concentrations of solutes are (molecules move from high to low concentration), what kind of membrane (if any) the molecules are moving through, and in many cases how large and charged the molecules are.
What condition does diffusion eventually lead in the absence of the other influences?
Diffusion will eventually result in equilibrium, where there is an equal distribution of particles or molecules throughout the space available. This occurs because diffusion naturally moves substances from areas of high concentration to areas of low concentration until the concentration is the same everywhere.
What is the general process in which molecules move from an area of higher concentration to an area of lower concentration?
This process is known as diffusion. During diffusion, molecules move spontaneously from an area of higher concentration to an area of lower concentration in order to achieve equilibrium. The movement continues until the concentration of the molecules is equal throughout the space.
The difference in concentration of a substance across space is called a?
The difference in concentration of a substance across space is called a concentration gradient. This gradient drives the movement of molecules from regions of higher concentration to regions of lower concentration through processes like diffusion or active transport.
Diffusion is defined as a movement of molecules?
Diffusion is the movement of molecules from an area of high concentration to an area of low concentration, driven by random thermal motion. This process results in the equal distribution of molecules in a given space over time.
What is the natural tendency of molecules to spread from an area high concentration to an area of low concentration?
Diffusion is the movement of molecules from a high concentration to a low concentration without using ATP (energy). A related term: Osmosis is the movement of water molecules from a high concentration to a low concentration without using ATP (energy). In contrast, active transport is the movement of molecules from a low concentration to a high concentration but DOES use ATP (energy).
What is cell diffusion?
One way that substances enter a cell is through diffusion. Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration. When the molecules are even throughout a space it is called equilibrium.
How does diffusion show that molecules are always moving?
How? Molecules move from an area of higher concentration to an area of lower concentration. When the concentration decreases (be it determines by a measure of pressure) in a unit volume; that indicates there are less molecules occupying that given space. So they must have gone somewhere...
What state does diffusion eventually lead to?
Diffusion leads to the state of equilibrium, where there is an equal distribution of molecules or particles throughout a system. At equilibrium, there is no net movement of particles from one area to another because the concentration gradient has been equalized.
What is the main way molecules move?
Molecules move by osmosis, diffusion, and active transport.OSMOSISOsmosis moves water from an area of high concentration to an area of lower concentraion.ACTIVE TRANSPORTActive transport moves sodium, calcium, and potassium from an area of low concentration to an area of higher concentration using energy.DIFFUSIONDiffusion moves other molecules from high to low concentraion.
What is the end result of diffusion or Osmosis?
The end result of diffusion is the equal distribution of particles or molecules across a space, moving from an area of higher concentration to one of lower concentration. For osmosis, the end result is the movement of water across a semi-permeable membrane to equalize the concentration of solute on both sides.
Describe the equilibrium potential of an element?
Is a condition in which the concentration of a substance is equal throughout a space.
What occurs when Molecules exchange places?
When molecules exchange places, they undergo a process known as diffusion. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration until equilibrium is reached. This movement allows molecules to mix and redistribute throughout a space.
