(a) ΔSsystem > 0,ΔSunivers < 0
(b) ΔSsystem > 0,ΔSunivers < 0
(c) ΔSsystem < 0,ΔSunivers > 0
(d) ΔSsystem < 0,ΔSunivers < 0
Correct Answer:
ΔSsystem < 0,ΔSunivers > 0
Explanation:
If heat flows from system at temperature T(system) to the surrounding at temperature T(surr) then ΔS(sys) < 0 , ΔS(surr > 0.
