How does a solid become a liquid ?
I get an example of an ice . When the molecules of the ice shake faster until it gets at 0 Celsius the molecules begin to separe or brake up from one to another .thei neighboring molecules can no longer hold them in place then the crystal structure begins to collaps and the ice become a swarm whit water floowing so here is geting in liquid state in this point is call melting point
Freezing
Is the revers of the example I have did before . As the liquid becomes to cool the particles go slow and get more closer by the time it pass.in this piont we can call him freezing point . As the time it pass the crystalline solid is bing forming .
When the liquid is becoming a solid the temperature is falling and the liquid becomes more viscous as its temperature decreases until it get in an brittle glass
