5.
A system experiences the following changes in entropy while
undergoing non-adiabatic processes:
i)
a decrease in entropy during a reversible process.
ii)
an increase in entropy during a reversible process.
iii)
a decrease in entropy during an irreversible process.
State, giving reasons, whether you expect the entropy of the
surroundings to increase or decrease.
[ i) increase, ii) decrease, iii) increase ]
