2.Brownian movement is maximum in gases .

3.Cohesive forces are negligible in gases .

4.Matter can change from one state to another by change in temperature or pressure.

5.The space between atoms(molecules) of solid is minimum .

6.Intermingling of molecules is called diffusion .Ice on absorption of heat converts to 'X' a procee called melting . 'X' changes to water vapour on heating . Water vapour changes back to 'X' on condensation . The constant temperature at which ice changes into 'X' is called its fusion point .
