What is the difference between glass transition temp and melting point?

∙ 12y ago
Glass transition point describes the temperature when material (crystalline or semi-crystalline) loses its crystallinity but not necessary melts. For instance, polyethylene's glass transition temperature is around -140-150C, while its melting temperature is around 105-130C (light and heavy species).

Do amorphous solids have specific melting points?
They have a glass transition.
What is the melting point of glass rod?
The melting point of glass rods can vary depending on the composition of the glass. However, most common types of glass rods have a melting point between 1300°C and 1500°C (2372°F to 2732°F).
What is the glass transition temperature of polyacrylate?
Depending on the polymerization, the glass transition temperature will be between -13 C and -8 C; that's 8.6 F to 17.6 F.
What do understand by glass transition temperature. Explain whether it is exothermic or endothermic?
glass transition is a change in state. when the state changes from crystalline or rather glassy to a rubbery like state. it should be noted that it is not melting. it is a state change and not a phase change. it is endothermic phenomena because heat is given to a system so that glass transition occurs. because no heat is released during the process it can not be considered to be endothermic.
What is the glass transition temperature of silk?
The glass temperature transition is for glass, polymers, etc. (amorphous or semicrystalline materials), but not for leather.

They have a glass transition.
Melting glass is an example of what?
Wastefulness.But seriously folks....It is a glass transition of glass-forming liquid into glass which occurs upon rapid cooling.
What is the answers of TM and tg in chemistry?
Tm is temperature of melting. Tg is glass transition temperature.
What is the melting point of glass rod?
The melting point of glass rods can vary depending on the composition of the glass. However, most common types of glass rods have a melting point between 1300°C and 1500°C (2372°F to 2732°F).
What is glass transition?
The glass transition is a second order phase transition. For materials that have a glass transition temperature, below it they are hard and brittle and above it they are softer and "rubbery".
What is the melting point of a Pyrex test tube?
A glass hasn't a true melting point. The softening point of Pyrex glass is between 800 °C and 850 °C.

What is the difference between auto glass and regular glass?
The difference between auto glass and regular glass is that auto glass has a thin layer of flexible clear plastic placed between two (or more) layers of glass. The film holds the glass in place when it breaks and will lessen the injuries from broken glass.
Is polyethylene glass transition?
Low-density polyethylene does exhibit a glass transition at around 150K.
What is the difference between ceramics and glass?
Usually ceramics is not transparent and glass is
