underset(P_(1), V_(1), T_(1))("State") A overset("Rev")rarr underset(P

1.	underset(P_(1), V_(1), T_(1))("State") A overset("Rev")rarr underset(P_(2), V_(2), T_(2))("State B"): If P_(1) = P_(2) then
Answer» `underset("UNIVERSE")(Delta S) = 0` `underset("universe")(Delta S) = 1` `underset("universe")(Delta S) GT 0` `underset("universe")(Delta S) lt 0` Solution :For reversible ISOBARIC process `Delta underset("SYSTEM")(S ) = nc_(P) "ln" (T_(2))/(T_(1)), Delta underset("surr")(S) = - nc_(P) "ln" (T_(2))/(T_(1))` `:. Delta underset("universe")(S) = 0`
