Diffusion is more rapid in less dense medias. Molecules have more open space that way and can move faster and more freely.
...more dense particles to an area of less dense particles
More dense.
Vinegar, it's less dense. Vinegar, it's less dense.
Particles have to move from a more dense area to a less dense are.

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.
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
...more dense particles to an area of less dense particles
More dense.
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.
It depends what yo compare it to.
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
