together
c)
alpha, beta and S2 exist all
together
d)
none of the above​

Answer 1

the temperature at which a sudden change of physical properties occurs, such as a change of phase or crystalline structure, or at which a substance becomes superconducting.

There is a certain temperature(different for each polymer) called the glass transition temperature, or Tg for short. When the polymer is cooled below this temperature, it becomes hard and brittle, like glass. Some polymers are used above their glass transition temperatures, and some are used below.
