A closed system undergoes an irreversible process from state 1
to state 2 during which it absorbs heat in the amount of Q
from its surrounding maintained at a temperature T. If the
entropy of the system is S1 at state 1 and
S2 at state 2, which of the following statement
is correct for this process?
ΔS > S2 – S1 + Q/T
ΔS = S2 – S1 + Q/T
ΔS > S2 – S1
ΔS = S2 – S1
ΔS < S2 – S1
