Question

make a model to explain the structure of  particles in solids liquids and gases

Answer 1

take some thermocol colour thermocol balls or some beads or some circular kundans for solids arrange  those balls without spaces because solids donot have spaces between them liquids leave some space and arrange and for gases leave very much gap.in solids particles are tightly arranged without any spaces ex:-wood,box,bench etc.in liquids  solids have  a little gap between them and take the shape of the container in which they are poured.eg:petrol,water etc.gases have large spaces between them.and also have high diffusion property

Answer 2

take some small balls & colour it the colour of your choice. stick it very nicely to show solids. do the same with liquids but leave some space between them. do the same with gas but spread them on the ground.
