Question

Give reasons for the following:
An unit increase stick gives smell only when we come close to it but on lighting the stick we get smell even far away from it.why?​

Answer 1

Answer:

Due to diffusion as we light it the smell diffuses and we can even smell far away from it.

Answer 2

Answer:

Due to the rapid diffusion of its molecules.

Explanation:

An unit intense stick gives smell only when we come close but on lighting the stick we get smell even far away from it.

Because the lighting of intense stick make its molecules to diffuse rapidly with air molecules and by the help of air molecules it reached to our nose even it get felt far away from it.

The molecules of intense stick change in vapours state and get diffused or mixed with air molecules which make it easier to moves from one place to another.

Diffusion :- It is the gradually mixing of two or more molecules having different densities against the action of gravity is called diffusion.

And due to this property gases molecules diffused faster in air medium.
