What is Supercooled liquid?How glass comes out to be Supercooled liquid?As far as i know Supercooling is the process of chilling a liquid below its freezing point, without it becoming solid.But glass looks like solid.Please explain

Please look for information and read about "glass transition". It is different from freezing/melting, even if the initial and final states seem to be identical.

Glass is an amorphous(i.e. non-crystalline) solid, not a liquid, similarly you can have amorphous silicon and amorphous metals. As Borek said you should look at the glass transition for more information.
