Question

Which statement best describes the motion of

Answer 1

The dye molecules  move in a directed way from high to low  concentration

Explanation:

The statement that best describes the motion of dye molecule in water is directed from a region of high to low concentration. The motion of the particles of the dye in water is described as diffusion:

• diffusion is the movement of molecules of a substance from one position to another.
• diffusion occurs from a region of high concentration to that of a low concentration.
• the dye in the water solution causes an increase in concentration of an area where it is dropped.
• this causes the particles to spread outward in the solution.
• a concentration gradient is set up between the two parts of the solution.
• this gradient facilitates the movement of the dye particles.
