You can smell perfume because it diffuses into the air and makes its way into your nose.

Example of gas diffusion. Different kinds of membranes allow differing amounts of diffusion to occur. Sugar gets dissolved evenly and sweetens the water without having to stir it. Burning of incense stick is an example of diffusion of gas.

Many agricultural industrial and mechanical processes rely on the ability to produce other stuff as waste. The related process effusion is the escape of gaseous. What is an example of gas diffusion.

Following formula shows ratio of diffusion rates of two gases at same temperature. Gaseous diffusion is based on Grahams law which states that the rate of effusion of a gas is inversely proportional to the square root of its molecular mass. Placing food coloring in a liquid will diffuse the color.

Here is an example to understand the diffusion of gases. Take a container separating it into two partitions. Similarly if a canister of liquid nitrogen leaks a little nitrogen gas that escapes would quickly diffuse into the atmosphere.

A spray of perfume or room freshener will get diffused into the air by which we can sense the odour. You can smell perfume because it diffuses into the air and makes its way into your nose. The molecules of gas A and B are in continuous random motion in its respective compartments.

Smell of a perfume or meal in a room are some common examples of diffusion of gases. Think about a helium balloon. If there are a greater number of A molecules near point 1 than at 2 then since molecules diffuse randomly in direction more A molecules will diffuse from 1 o 2 than from 2 to 1.
