Girdhar Arora 4 years, 3 months ago

Yes the three states of matter and inter - convertible because they can change state Let us take an example which is most common- Ice when heated for some time converted to water (fusion)and water when heated converted to gas (vaporisation )and when liquid is freezes it converted to ice as solid(freezing ) and when gas particles collide with cold substance they converted to liquid (condensation )and when gas is directly converted to solid or vice - versa (shows by only some substance like camphor and ammonium chloride) it is called sublimation This how the states interconnect

Arpit Giri 3 years, 3 months ago

Due to the property of diffusion in gases an inflated air balloon deflates when pricked with a pin. Diffusion property in gases is very fast. The molecules in a balloon are under higher pressure and their concentration is higher (packed more closely together) hence the diffusion from inside to outside takes place, but by the very nature of diffusion outside to inside takes place very fast, when pricked with a pin making the balloon to deflate.
