glass transition is a phase transion of secound order........for rubbery materials there is no change in order of molecular state takes place........i.e,the short range orderness of the material remains in the glassy state also.......thus, there is no sharp change of specific volume with decrease in temp. is recorded....which makes g.t. a less sharp transition.....
What else can I help you with?
What is the glass transition of Teflon?
Teflon does not exhibit a distinct glass transition temperature, as it is a non-crystalline polymer. Instead, it transitions directly from a glassy to a rubbery state as it is heated due to its amorphous structure.

Obsidian is a volcanic glass that often forms with sharp edges due to its rapid cooling process. Its conchoidal fracture gives it razor-sharp edges that have been historically used for cutting tools and weapons by various cultures.
Why is glass so sharp?
Glass is sharp because of its molecular structure. When glass breaks, it forms jagged edges and sharp points because the molecules in glass are arranged in a way that allows them to easily break apart into sharp pieces.
