Chemical Engineering Thermodynamics
High pressure steam is expanded adiabati-cally and reversibly through a well insulated turbine, which produces some shaft work. If the enthalpy change and entropy change across the turbine are represented by ΔH and ΔS respectively for this process:

Δ H = 0 and ΔS = 0
Δ H ≠ 0 and ΔS ≠ 0
Δ H ≠ 0 and ΔS = 0
Δ H = 0 and ΔS ≠ 0

Chemical Engineering Thermodynamics
A large iceberg melts at the base, but not at the top, because of the reason that

The iceberg remains in a warmer condition at the base
Ice at the base contains impurities which lowers its melting point
Due to the high pressure at the base, its melting point reduces
All of these
