Chemical Engineering Thermodynamics
Critical solution temperature (or the con-solute temperature) for partially miscible liquids (e.g., phenol-water) is the minimum temperature at which

Two liquids are completely separated into two layers
A homogeneous solution (say of phenol water) is formed
None of these
Mutual solubility of the two liquids shows a decreasing trend

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

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