User: What is the primary cause of diffusion? some substances can dissolve in solvents heat added to a substance random internal motion of atoms and molecules attraction of opposite atomic charges Weegy: Primary cause of diffusion is random internal motion of atoms and molecules. User: What is meant by elastic collisions? heat given off by constant collisions compression of the gas resultant force of all collisions collision and rebound without loss of energy
Diffusion is driven by the random movements of individual molecules in solution. If the concentration of a molecule is greater outside a cell than inside the cell then, on average, more molecules will randomly enter the cell, than leave the cell.
