Question & Answer
Choose the Best Answer
Tg determines if a polymer can maintain its rigidity at high temperatures.
Tg indicates the temperature at which a polymer will combust.
Tg has no effect on the flexibility of polymers at room temperature.
Tg only affects the mechanical properties of polymers when they are frozen.
Understanding the Answer
Let's break down why this is correct
Tg is the temperature at which polymer chains begin to move more freely. Other options are incorrect because Some think Tg indicates when a polymer will burn; It is a misconception that Tg only matters at high temperature.

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.
