Question

At the ________ a liquid changes into solid.

• A. liquefaction point
• B. freezing point
• C. boiling point
• D. sublimation point

Answer 1

The correct option is B freezing point

Pure, crystalline solids have a characteristic melting point, the temperature at which the solid melts to become a liquid.

Liquids have a characteristic temperature at which they turn into solids, known as their freezing point. In theory, the melting point of a solid should be the same as the freezing point of the liquid.
