Question
Classify each process by its individual effect on the entropy of the universe, S.
Drag the appropriate items to their respective bins: Increases S of the Universe, Does not Affect S of the Universe, Decreases S of the Universe.
a process run infinitesimally slowly at equilibrium and reversed to its original state
a constant composition mixture of solid and liquid water at STP (273.15 K and 1 atm)
motion of a frictionless pendulum
a bag of red marbles and a bag of green marbles dumped together on a table top
ice melting to water above the melting point
sublimation of naphthalene
(mothballs)

Explanation / Answer
Does not Affect S of the Universe
a process run infinitesimally slowly at equilibrium and reversed to its original state
a constant composition mixture of solid and liquid water at STP (273.15 K and 1 atm)
motion of a frictionless pendulum
Increases S of the Universe
a bag of red marbles and a bag of green marbles dumped together on a table top
ice melting to water above the melting point
sublimation of naphthalene
Explanation :
Entropy means diorder. if random ness of the molecules increasesm then entropy increases.
