Acohesive force is best described as the a cohesive force is best described as the attraction between two liquid molecules force that holds together the nucleus attraction between a liquid molecule and a solute attraction between molecules of two different substances force that allows for molecular cohesion

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
