Glass Transition Temperature (Tg)
Melting Point
Boiling Point
Crystallization Temperature
Understanding the Answer
Let's break down why this is correct
When heat adds energy, the tiny chains inside the polymer can move more freely, turning a stiff material into a soft, rubbery one. Other options are incorrect because Many think the polymer becomes rubbery right when it melts, but melting turns the solid into liquid, not just softer; Boiling is about a liquid turning to gas, which occurs much later than the softening.

Definition
Polymer Glass Transition Temperature (Tg) is the temperature at which a polymer transitions from a rigid, glassy state to a flexible, rubbery state. Understanding Tg is crucial as it determines a polymer's properties like flexibility and brittleness, impacting real-world applications such as the Challenger shuttle disaster.
