Diffusion is more rapid in less dense medias. Molecules have more open space that way and can move faster and more freely.
In terms of diffusion rates, liquid water diffuses the fastest due to its fluid nature, allowing molecules to move freely and quickly. Water vapor follows, as gas particles have higher kinetic energy and can spread rapidly, although they are less dense than liquid water. Ice diffuses the slowest because the molecules are locked in a rigid structure, restricting their movement significantly compared to the other states.
Particles have to move from a more dense area to a less dense are.
More dense objects settle faster than less dense objects. This is because denser objects have more mass and therefore experience a greater force of gravity pulling them downward, causing them to settle more quickly than less dense objects.
Vinegar, it's less dense. Vinegar, it's less dense.

Diffusion is the movement of molecules from more concentrated to less concentrated. Think of pouring dye into water it spreads out from a dense concentration of dye to the water surrounding it with little or no die (less concentration). Once it diffuses evenly it reaches equilibrium. It does NOT however stop moving. Source: Biology major
When ammonia diffuses woth hydrochloric acid, the ammonia is less dense than the Hydrochloric acid, thus causing the ammonia to travel faster towards the hydrochloric acid. A white solid ring should form when both gases meet.
It depends what yo compare it to.
Gas molecule always move. The movement is called Brownian Motion, a random behaviour of molecule and atom in fluid state. These little motion enhance diffusion even without any additional driving force. Gas had less interaction force than liquid and so the speed of motion is a lot greater and so higher diffusivity.
The higher the viscosity, the slower the rate of diffusion. Think of a liquid trying to diffuse through a plate of water (low viscosity) versus a liquid trying to diffuse through a plate of agar (high viscosity)

Everything has a density
Sugar is less dense than salt, leading to it dissolving faster.
