Rubber bands comprise of loosely packed chains of atoms.When stretched, the chain of atoms get neatly lined up in rows and hens the entrops of system decreases whereas when contacted the chains get tangled up in a mess increasing entropy of system. Also on strectching rubber band, it is observed that any substance brought in its contact gets heated up. Based on this information, answer the following questions.
Which of the following statement (s) is/are true regarding the change
`"Rubber band"_("streched") rarr "Rubberband"_("unstreached")`?
A. The change is spontaneous.
B. The process is endothrmic in nature.
C. Entropy of the rubber band is increasing in the process.
D. Entropy of surroundings is decreacing in the process.
