In this case the entropy increase.
The entropy change when a solution is formed from a liquid and a solid generally increases. This is because the solid dissolves in the liquid, leading to a greater dispersion of molecules and an increase in disorder within the system. The solid's structured lattice breaks down, allowing for more possible arrangements of particles in the solution, which contributes to a higher entropy state.
In this case the entropy increase.
The entropy change (( \Delta S )) from liquid to solid can be expressed as ( \Delta S = S_{\text{solid}} - S_{\text{liquid}} ), where ( S_{\text{solid}} ) is the entropy of the solid phase and ( S_{\text{liquid}} ) is the entropy of the liquid phase. Since solids are generally more ordered than liquids, this change is typically negative, indicating a decrease in entropy as the system transitions from a higher disorder (liquid) to a lower disorder (solid). This decrease reflects the loss of molecular freedom and arrangement during the solidification process.
usually a change in temperature.... OR PRESSURE Which all mean a change in entropy of the system
The melting equation describes the phase transition of a substance from solid to liquid as it absorbs heat. It typically involves the relationship between temperature and pressure, often represented in the context of the Gibbs free energy, where the change in enthalpy equals the product of temperature and change in entropy. The equation can be expressed as ( \Delta G = \Delta H - T\Delta S ), where ( \Delta G ) is the change in Gibbs free energy, ( \Delta H ) is the change in enthalpy, and ( \Delta S ) is the change in entropy. At the melting point, the Gibbs free energy change is zero, indicating equilibrium between the solid and liquid phases.
In this case the entropy increase.

the entropy of water is higher than the entropy of ice.

The change in entropy when an icicle melts at 2 degrees Celsius is positive. This is because the solid ice undergoes a phase change to become liquid water, increasing the randomness and disorder of the molecules, leading to a higher entropy.
Assuming you mean can entropy be reduced; the answer is yes. Only in an open system such as our planet. The universe is a closed systems. The entropy of the universe cannot be reduced. Chemical changes can reduced entropy in an open system. When gas turns into a liquid or when a liquid turns into a solid; entropy is reduced.
delta s (change in entropy) is positive when.... -you go from a solid to a liquid -you go from a liquid to a gas -when you go from a solid to a gas -when there are more mols of products than mols of reactant the change in entropy is negative when the reverse of the above happens
The entropy of a system typically decreases during the condensation of water. This is because the molecules of water vapor become more ordered as they transition into the liquid state, reducing the overall disorder (entropy) in the system.
