Technically the particles are moving randomly in all directions, its just that after some time this random movement causes them to spread out, giving the appearance that they are moving directly to the place of lower concentration.
Do you need more detail?
Hope this helps!
higher concentration (pressure)
Movement of particles (iron or molecules) from an area of higher concentration to an area.
Particles don't get bigger, however they fill a larger volume when turned into gas, this is because of diffusion, this is when particles in a higher concentration move to a lower concentration, this happens everyday in your body and in the domestic house hold
Solids, in general (water is an exception),contain a higher concentration of thermal energy per unit volume than liquids ...and both solids and liquids contain a higher concentration that gasses.
Heat=energy. The higher the heat, the higher the energy. Particles travel faster because they have more energy.
higher concentration to a area of lower concentration
Diffusion is the movement of particles from a region of higher concentration to a region of lower concentration. Osmosis is the diffusion of water molecules (only) from an area of higher concentration to an area of low concentration.
Diffusion
You think probable to diffusion.
Osmosis
This process is known as diffusion.
No. Diffusion is the process in which particles move from where they are in higher concentration to where they are in lower concentration.
Diffusion is the passive movements of particles from an area of higher concentration to an area of lower concentration. Osmosis is the movement of water molecules across a partially permeable membrane from a region of higher water concentration to a region of lower concentration.
DiffusionThe movement of particles from a region of higher concentration to a region of lower concentration is called diffusion. However, the movement of water through a semi-permeable membrane (from an area of high concentration to an area of low concentration) is specifically called osmosis.
