1- put an unlit incesnse stick in the corner of your room,try to smeel it siiting far from it.Now light the incense stick and try now to GET the smell You would observe now that  you are able to smell it from a distanceThus particles get diffused and thus less force of attraction and the are always moving.2- open a water TAP and try breaking the stream with your hand .Were you able to do so? No because particles of matter have a force of attraction between them.3-gases are easily compressible because of large intracellular spaces between THEMAND thus speed of particles is higher. Tru out filling a syringe.4-TAKE 2-3 crystals of KMNO4 and dissolve in 100 ml of water.take out 10ml of this sol and put into 90ml of water.now take out 10ml of this sol again and put into 90ml of water. We observe that as we are doing this again and again,colour of the solution becomes lightThis concludes that there must be millions of TINY particles in just a few crystals which are also dividing in to smaller and smaller particles.HOPE IT HELPSPLEASE MARK ME AS BRAINLIEST
