Question

During which phase change does the arrangement of water molecules become more orderly?

Answer 1

The arrangement of water molecules become orderly during $\boxed{{\text{B}}{\text{. freezing}}}$.

Further Explanation:

Phase transition is defined as the change from one state to another state but no change in chemical composition is observed. It is also known as a phase change, state change or physical change.

A. Melting

It is the process in which a substance transforms from its solid state to the liquid state. This is also known as fusion. The strong bonds between the solid particles get broken down to form liquid that has weaker bonds than the former state.

B. Freezing

It is a phase transition in which liquid gets converted into solid by lowering its temperature. Here, the weaker forces between liquid particles are replaced by the strong forces that occur between solid particles.

C. Boiling

It is the process that takes place when a liquid gets converted into its vapors. This is done by heating the liquid up to its boiling point. Here, the weak forces between liquid particles are replaced by the weaker forces that occur between gas particles.

D. Condensing

This process comes into account when vapors are converted into the liquid state. This is done by changing temperature and pressure of the substance. Here, the weaker forces between liquid particles are replaced by slightly stronger forces that occur between liquid particles.

Due to strong intermolecular forces, the particles are more orderly arranged in solids than any other state of matter. Since solid is formed in case of freezing. So option B is correct.

Answer 2

The phase change in which the water molecules become most orderly is the freezing. This is the process of changing water as liquid to its solidified form. The process of freezing is an exothermic which means that for this to occur, heat should be removed from the system.
