Question & Answer
Choose the Best Answer
Tg indicates the temperature where a polymer becomes a good electrical conductor.
Tg determines the temperature range where a polymer exhibits rubbery behavior, affecting its flexibility and applications.
Tg is the temperature at which polymers lose all their molecular weight.
Tg signifies the point where polymers become insoluble in solvents.
Understanding the Answer
Let's break down why this is correct
Tg is the temperature where a polymer switches from a hard, glassy state to a soft, rubbery state. Other options are incorrect because The idea that Tg means a polymer starts conducting electricity is a misunderstanding; The misconception that polymers lose weight at Tg is incorrect.
