State that the energy for diffusion comes from the kinetic energy of random movement of molecules and ions

Energy Source for Diffusion

The energy that drives the process of diffusion originates from the kinetic energy of the random movement of molecules and ions.

Key Points

1. Kinetic Energy:
   • Molecules and ions are in constant motion due to their thermal energy. This motion is characterized by random movements in various directions, which is a result of their kinetic energy.
2. Random Movement:
   • The random movement of particles leads to collisions and interactions, causing them to spread out over time. This randomness is essential for diffusion, as it allows particles to move from areas of higher concentration to areas of lower concentration.
3. Driving Force:
   • As particles move randomly, those in a more concentrated area are more likely to collide with neighboring particles and move into less concentrated areas. This results in a net movement down the concentration gradient.
