Question

which process is opposite to diffusion i.e evaporation or compression

Answer 1

Reverse diffusion. Reverse diffusion refers to a situation where the transport of particles (atoms or molecules) in a medium occurs towards regions of higher concentration gradients, opposite to that observed during diffusion. This phenomenon occurs during phase separation and is described by the Cahn–Hilliard equation .

Answer 2

afcource compression is opposite of diffusion as in compression the molecules or particles are not allows to go at lower concentration area from higher concentration area
