of the other people. If you spray air freshener into the bathroom and theplace where the farting took place, the air freshener spray dispersesall over. this is diffusion as well.
1) A tea bag placed in a cup of hot water will diffuse into the water
2)placing food colouring in a liquid will diffuse the colour
3)cigarette smoke diffuses into the air
4)you can smell perfume because it diffuses into the air and makes its way into your nose
Hope this helps you ^_^
Here Is Your answer
Three Examples Of Diffusion Of Solid To Another Solid
1.When chalk marks are left on the black board for a long time they eventually become permanent.
2.Two peices of chalk kept tightly together will fuse after a few years.
3.Pure gold and pure lead will diffuse into each other.
Now,For Examples Of Diffusion In Solids :
Diffusion can take place in gases, liquids, or solids. In solids, particularly, diffusion occurs due to thermally-activated random motion of atoms - unless the material is at absolute zero temperature (zero Kelvin), individual atoms keep vibrating and eventually move within the material.
ii) A teabag placed in a cup of hot water will diffuse into the water.
iii) Placing food coloring in a liquid will diffuse the color.
iv) Cigarette smoke diffuses into the air. These are some common examples of diffusion of gases.

A tea bag placed in a cup of hot water will diffuse into the water.
Cigarette smoke diffuses into the air.
qa = 3x10⁻⁸ c
qb = -6x10⁻⁸ c
qc = 2x10⁻⁸ c
rab = 3 cm = 3x10⁻² m
rbc = 6 cm = 6x10⁻² m
asked: f at point b?
coulomb force of charge a and b
fab = k qaqb / rab²
= 9x10⁹ x 3x10⁻⁸ x 6x10⁻⁸ / (3x10⁻²) ²
= 9x10⁹ x 18x10⁻¹⁶ / 9x10⁻⁴
= 18x10⁻³ n
coulomb force charge c and b
fbc = k qbqc / rbc²
= 9x10⁹ x 6x10⁻⁸ x 2x10⁻⁸ / (6x10⁻²) ²
= 108x10⁻⁷ / 36x10⁻⁴
= 3x10⁻³ n
so the coulomb force at point b = fab - fbc
= 18x10⁻³ - 3x10⁻³
= 15x10⁻³ n
= 1.5x10⁻² n
