If a small amount of dye is placed in a beaker of water, it will flow away from the initial point of contact. The ensuing process illustrates:

A) diffusion.
B) concentration.
C) charge.
D) electrostatic pressure.

Diffusion

The process by which molecules move from an area of higher concentration to one of lower concentration.

Dye

A substance used to impart color to materials, such as textiles, paper, and other substrates, through a process of absorption or chemical bonding.

Electrostatic Pressure

The force exerted by the electrostatic field on charged particles, affecting their movement and distribution.
