Here's something to think about. As most of you know, glass is a liquid. Now over years it will move at a slow rate. As i was taking a walk the other day i thought (if I'm correct) if glass is extremely heated sand, why wont it ever go back into its original state when cooled and why won't it go to a gas if heated much higher?
What i thought was because when its heated, maybe it undergoes a special chemical reaction in which it cant go back. For example when you burn a piece of paper there no way you'll be able to get it back to the way it originally was.
as for the gaseous part, i was guessing you probably could but it'd have to be extremely extremely hot temperatures such as those in the center of the earth or at the sun.
I could look this up online but then, whats the fun in a blog then?
