Question & Answer
Choose the Best Answer
Tg represents the temperature where a polymer becomes more flexible.
Tg is the temperature at which all polymers become crystalline.
A lower Tg indicates that a polymer is more likely to remain rigid at room temperature.
Polymers with a high degree of branching, like LDPE, usually have a lower Tg.
Tg can influence the applications of polymers in various industries.
Understanding the Answer
Let's break down why this is correct
The glass transition temperature marks the point where polymer chains gain enough freedom to move, so the material becomes more flexible. Other options are incorrect because Tg is not about when polymers become crystalline; A lower Tg means the polymer will be more flexible at room temperature, not rigid.

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.
