Ankit Gupta Posted January 18, 2014 Posted January 18, 2014 Why do chewing gum get stiff when we put water ( mainly cold ) on it ?
swansont Posted January 18, 2014 Posted January 18, 2014 It's probably the cold. Chewing gum undergoes a glass transition and hardens/softens at some point below body temperature 1
John Cuthber Posted January 18, 2014 Posted January 18, 2014 It's a bit like the freezing point. http://en.wikipedia.org/wiki/Glass_transition
