Answer:

The correct answer is option B, that is, it undergoes a phase change.

Explanation:

A physical change occurs when a substance changes phase. The term phase change or phase transition is most generally used to illustrate transitions between the liquid, solid, and gaseous states of matter.

At the time of a phase change of a given medium, some of the features of the medium change, generally intermittently, as an outcome of the change of external conditions like pressure, temperature, or others. For example, a liquid may turn into a gas by getting heated to the boiling point, leading to a sudden change in volume.

The answer is: B. It undergoes phase change.

A physical change occurs when a substance changes phase.

For example, evaporization is phase change process in which the water changes from a liquid to a gas (water vapor).

Condensation is phase change process in which the water changes from a gas to a liquid.

If the arrangement of particles is changed, that is chemical change or chemical reaction (new substance is formed).
