Activity to demonstrate that diffusion means intermixing of particles
Answers
Explanation:
Activity:
To prove that the mixing speed depends on the attraction force between particles.
Procedure:
Take two water-filled beakers
Place a drop of ink on the first beaker's sides.
In the second beaker, place a drop of honey in the same manner.
Leave them and record the observation without disturbance.
We are going to observe that the attraction forces between the ink particles are weak, so they are quickly distributed evenly in water.
The attraction forces between the honey particles, on the other hand, are powerful and therefore they move slowly as a consequence it takes longer time for the honey particles to enter the water spaces.
Conclusion:
Particles of matter are moving continually, but the intermingling rate depends on the attraction forces between them.
