That takes energy.
Normal diffusion means that the molecules move away from each other
(in other words ... to where there are less molecules).
Mhm, yes they do
In a solid the molecules are tightly packed together all touching one another and vibrate; in a liquid the molecules are more loosely packed and more free to move around but they are still touching; in a gas the molecules are free to move where they please
Molecules actually move faster in liquid because they have more space between them to move about. That's why liquid can flow, and a solid cannot. =)
Particles move most rapidly in stream rather than in boiling water.This is because the molecules of gases are loosely arranged than the molecules of liquids.So there will be more free space for the molecules to move in gases than in liquids.
No,boiling water does not have oxygen . Cold water molecules move slowly meaning there is space between the molecules for more oxygen to dissolve. Hot water molecules move rapidly meaning the space between the water molecules is less avalible for the oxygen molecues to dissolve into.
Whether a material expands or contracts when it is heated can be ascribed to a property of the material called its entropy. The entropy of a material is a measure of the orderliness of the molecules that make up the material. When the molecules are arranged in an ordered fashion, the entropy of the material is low. When the molecules are in a disordered arrangement, the entropy is high. (An ordered arrangement can be thought of as coins in a wrapper, while a disordered one as coins in a tray.) When a material is heated, its entropy increases because the orderliness of its molecules decreases. This occurs because as a material is heated, its molecules move about more energetically. In materials made up of small, compact molecules, e.g., the liquid in a thermometer, as the molecules move about more, they push their neighbouring molecules away. Rubber, on the other hand, contains very large, threadlike molecules. When rubber is heated, the sections of the molecules move about more vigorously. In order for one part of the molecule to move more vigorously as it is heated, it must pull its neighbouring parts closer. To visualize this, think of a molecule of the stretched rubber band as a piece of string laid out straight on a table. Heating the stretched rubber band causes segments of the molecules to move more vigorously, which can be represented by wiggling the middle of the string back and forth. As the middle of the string moves, the ends of the string get closer together. In a similar fashion, the molecules of rubber become shorter as the rubber is heated, causing the stretched rubber band to contract
Molecules tend to move into areas where there are less molecules. This is called diffusion and can happen with or without energy.
diffusion- passive transport in cells where molecules move from an area where there are more molecules to an area of fewer molecules.
Diffusion is the word you're looking for.
molecules moves through concentration gradient .and molecules move either in the form of ions or gas in the medium
Molecules move from an area of higher concentraion to lower concentration by a process called "diffusion." When the molecules move from more to less concentration, it is called a "concentraiton gradient." When molecules move generally in one direction (towards one area), it is called "net direction."
Yes.
Process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated.
Heat makes molecules move. Alcohol, if used as a solvent, makes some molecules more mobile.

Diffusion is the form of passive transport that moves particles away from areas with more particles into areas with fewer particles.
