how does a solid become a liquid

 what happend when ice cube being heated whwn temperature rise water molecules shake faster when temperature is 0 c molecules begin to brake free then the crystal structure begins

to collapse and solid start flowing molecules this molecules become liquid temperature subtance change solid to liquid 

freezing

whit the process of melting crystalline salid can revesed if the liquid is cooled liquid cols particles slow down and come colser together freezing point when attractive force begin to trap particles

and crystals form liquid has become solid the temperature can continue to fall
