Question

Are any of the following phenomena reversible? Why or why not.

a.) Breaking an empty soda bottle,

b.) mixing a cocktail,

c.)melting an ice cube in a glass of iced tea,

d). evolution of a new animal species

e). puncturing an automobile tire,

f). writing this book.

Answer 1

a. breaking of an empty soda bottle is not a reversible process as entropy change in the process is +ve and generally speaking the processes with +ve entropy change when happening instantaneously are non reversible

b. mixing a cocktail is again from option a, an irrevcersible process
c. melting of ice cube is irreversibel for the smae reason from part a
d. evolution of a new specie is an irreversible process too
e. puncturing an automobile tyre is irreversible too
f. Writing a book is reversible too
