Question

Why doesn’t a broken wineglass spontaneously fix itself, from a thermodynamic point of view?

A.Fixing a wineglass is an endothermic change, requiring lots of heat.
B.Fixing a wineglass requires a large increase in entropy.
C.Fixing a wineglass requires a large decrease in entropy.
D.Fixing a wineglass is an exothermic change, producing lots of heat.

Answer 1

C. Fixing a wineglass requires a large decrease in entropy.

Answer 2

C.Fixing a wineglass requires a large decrease in entropy.

Step-by-step explanation:

Decrease in entropy is a non spontaneous process.

Entropy is the measure of randomness or disorder. For a process to be spontaneous the disorder or the randomness should increase. In a spontaneous process entropy increase or becomes positive.

A broken wine glass has more disorder than an unbroken glass. So a broken wine glass does not spontaneously fix itself as that would lead to a decrease in entropy.
