Diffusion. It also occurs in liquids, by the way.
Potassium permanganate particles diffuse into water molecules and the particles of potassium permanganate mix into water even without stirring. From the higher concentration to lower concentration.
An accelerant is a substance that speeds up the burning process of a material, such as gasoline or lighter fluid. It is commonly used in arson attacks to ignite fires quickly and spread them rapidly.
The process where an acid and a base neutralize each other are called neutralization reaction. The products of this process are a salt and water. For example:- NaOH + HCl -------> NaCl + H2O
Rutherford called the region in the gold foil experiment that deflected alpha particles the "nucleus." He discovered that the positive charge and most of the mass of an atom were concentrated in this small, dense region.
A substance with a high density has more mass packed into a small volume. This means that it is heavier for its size compared to a substance with lower density. Common examples include metals like lead or gold.
it is called a liquid
digestion
Particles moving from problem areas to less crowded areas are called diffusion. Diffusion is the process by which particles spread out and move from areas of high concentration to areas of low concentration to create equilibrium. This movement occurs due to the natural random motion of particles.
Phagocytosis is the process where cells engulf and ingest other cells or solid particles. Endocytosis is a general term for the process by which cells take in substances from outside the cell by engulfing them in a vesicle.
The solid part in a filtration process is called the residue or the retained particles. These are the particles that are left behind on the filter after the liquid has passed through.
Subsoil.
gas particles move fastly spread apart
That would be a description of heat transfer by conduction.
A stone smoothed by wind abrasion is called a ventifact. This process involves the wind carrying sand and other particles that erode the surface of the stone over time, resulting in a smooth and polished appearance.
The particles of light are known as photons.
If you did this the salt would probably dissolve. The mixture is a solution.
Cholera does not spread through air. But then cholera spread by housefly. You can call it spread by 'Air'.
