Characteristics of Particles of Matter
The important characteristics of particles of matter (like atoms or molecules) are the following :
(i) The particles of matter are very, very small
(ii) The particles of matter have spaces between them
(iii) The particles of matter are constantly moving
(iv) The particles of matter attract each other
We will now perform some simple experiments to show all the characteristics of the particles of matter.The samples of matter (or materials) which we will be using for performing these experiments are potassium permanganate, water, sugar, incense stick (agarbatti), air, copper sulphate, a piece of chalk, ice and an iron nail.
