Question

Which process refers to the change of state from liquid to solid?

• A. Boiling
• B. Freezing
• C. Melting
• D. Condensation

Answer 1

The correct option is B

Freezing

The explanation for the correct option:

(B) Freezing:

• It is the process in which the phase transition of a substance from a liquid to a solid state when the temperature of a substance is lowered below its freezing point.
• For example, the conversion of water to ice upon lowering its temperature.

The explanation for the incorrect option:

(A) Boiling:

• Boiling is the change in which the liquid phase to the gas phase on heat absorption at a constant temperature.
• For example, the Boiling of water and converting it into vapors.

(C) Melting:

• The process in which a substance changes from a solid state to a liquid state is referred to as melting.
• For example, the melting of ice into water.

(D) Condensation:

• The process by which the physical state of matter changes from gaseous to liquid is known as condensation.
• ]When water vapor in the air comes into contact with a colder surface, condensation occurs.

Thus, the correct option is an option(B).
