What is the name of the process when molecules move to a less concentrated area called?
Diffusion, unless it is water, in which case it is osmosis.
Why is the collision frequency in a gas likely to less than in a concentrated liquid?
Molecules or atoms in a gas are farther apart than in a liquid, so the collision frequency is lower.
What is the processby which substances move from areas of higher concentrationto areas of lower concentration?
More concentrated to less concentrated
Why is diffusion important for all living things?
Diffusion is the movement of molecules from an area where they are more concentrated to an area where they are less concentrated. In other words, diffusion occurs when concentrated molecules spread out and become more randomly distributed. Diffusion is important for all living things because it helps cells get materials they need, and get rid of wastes they don't need. If food is concentrated outside of cells, it can diffuse into cells. Water also diffuses in and out of cells depending upon the concentration of other molecules in the environment. The diffusion of ions is essentially for the proper functioning of nerve and muscle cells. Your body also relies upon diffusion to move oxygen from your lungs into your tissues, and in the processing of wastes in your kidneys. Basically, all living things rely upon the process of diffusion to move molecules from one place to another.
How much solute is in diluted solutions?
less then 0.01M
What is disfussion?
Process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated.
Why give an isotonic solution?
When comparing solutions, those that have the same concentration are isotonic. One that is more concentrated is hypertonic; less concentrated is hypotonic.
How do 0.5M and 2.0M aqueous solutions of NaCl differ?
0.5M is less concentrated than 2.0M.
Why can color be used only for comparing similar solutions and not comparing different solutions?
Concentration. If the color is dark then its more concentrated and lighter means less

What is a short definition of osmosis?
A process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.
What is passive membran transport?
The diffusion of substances across a membrane is called passive transport. Molecules move from where the substance is more concentrated to where it is less concentrated.
Molecules tend to move from an area where they are more concentrated to an area where they are less concentrated This process is called?
Diffusion

How do sponges breathe?
A sponge gets its oxygen from the water. The oxygen moves from the water to the sponge by a process called diffusion. Diffusion is when molecules of a substance move from an area where they are highly concentrated (where there are a lot of oxygen molecules) to an area where they are less concentrated (where there are not a lot of oxygen molecules). Oxygen is more highly concentrated in the water then in the sponge. Therefore, the oxygen goes from the water to the sponge.
When a protein channel allows molecules to cross through the cell membrane?
when a protein channel allows molecules to cross through the cell membrane this is called facilitated diffusion. many might mistake this for diffusion which is the process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated.
Why did whole milk move?
The whole milk moves because of diffusion.The molecules of milk diffuse thorugh the water as in simple diffusion, molecules diffueses from where it is more concentrated to where it is less concentrated to where it is less concentrated (diffusing down its concentration gradient). This leads to dynamic equilibrium; the solute molecules of mile continue to cross the membrane but at equal rates in both directions. Diffusion is a spontaneous process, needing no input of energy. No work must be done to move substances down the concentration gradient.
