i. Burn one end of the straw and let the smoke fill the smoke cell from the other end.
ii. Remove the straw and cover the cell using the cover plate.
iii. Illuminate the cell and with the use of a microscope observe the behavior of the smoke particles in the
smoke cell.
Observation
Bright specks which are in continuous random motion are observed.
The bright specks are smoke particles scattering light. The random motion is due to constant collision between
smoke particles and invisible air particles and also with walls of the cell.
