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 the spreading out of the particles of a gas or any substance in solution. It is caused by the random movement of the particles. The higher the temperature, the faster the particles move and the faster diffusion takes place.Diffusion results in the overall (net) movement of particles from an area of high concentration to an area of low concentration down a concentration gradient.ctive transport is used to move substances into cells and out of cells. Cells which carry out a lot of active transport often have lots of mitochondria to give them the energy they need. Active transport is important in the kidney for hanging on to the substances needed by the body such as glucose and some sodium ions.
