The phase with the lowest entropy is the solid phase. In solids, particles are closely packed in a structured arrangement, limiting their movement and reducing disorder. In contrast, liquids and gases have higher entropy due to greater particle freedom and randomness in their arrangements. Thus, solids exhibit the least amount of entropy among the three phases.
True. When a liquid is converted to a gas, there is an increase in entropy. This is because the gas phase typically has higher entropy due to the increased freedom of movement and the number of microstates available to the molecules in the gas phase compared to the liquid phase.
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.
The entropy of a gas is typically greater than the entropy of a liquid due to the increased molecular randomness and freedom of movement in the gas phase compared to the more ordered structure of a liquid. The higher entropy of a gas reflects its greater number of possible microstates and therefore its increased disorderliness.
When a liquid crystallizes to a solid, the sign of entropy is negative. This is because the process involves a transition from a disordered state (liquid) to a more ordered state (solid), resulting in a decrease in the randomness or disorder of the system. Consequently, the entropy of the system decreases during this phase transition.
The four phase symbols in chemistry are (s) for solid, (l) for liquid, (g) for gas, and (aq) for aqueous (dissolved in water). These symbols are used to indicate the physical state of a substance in a chemical reaction or process.

When water vaporizes, it increases in entropy because it transitions from a more ordered, liquid state to a more disordered, gaseous state. This increase in disorder leads to a higher entropy of the system.
entropy is greater the more possible arrangements for energy there are, which increases as the molecules become more mobile, so entropy is high in a gas, lower in a liquid, and lowest in a solid.

The gas phase. That is true of any substance. Gases, because they are free to move about the entire volume of any container have much more entropy than either liquid or solids (and liquids have more than solids). The more ways the atoms are free to move around, the more entropy they have.
Entropy is a measure of the disorder or randomness in a system. The phase of matter with the highest entropy is generally considered to be the gas phase, as the particles in a gas have the highest degree of freedom and randomness compared to liquids and solids.
When water freezes, the structure changes from a more disordered liquid phase to a more ordered solid phase, with water molecules forming rigid ice crystals. This increase in order leads to a decrease in entropy.

Pressure changes have no effect on the entropy of substances in the solid or liquid states. Entropy is primarily affected by temperature changes and phase transitions rather than pressure variations in these states.
