Question

Which of the following is a definition of glass transition temperature?

a. The temperature at which a glass transforms from a liquid to solid.
b. The temperature at which there is a slight decrease in the slope of the temperature versus specific volume curve.
c. The temperature at which a glass transforms from a solid to liquid.

Answer 1

c. The temperature at which a glass transforms from a solid to liquid.

Step-by-step explanation:

The glass transition temperature is said to be a temperature range when a polymer structure transition from a glass or hardy(solid) material to a rubber like or viscous liquid material.

The glass transition temperature is an important property that is critical in product design.
