What do we call the temperature at which a solid changes state to become a liquid?
A) Freezing point
B) Boiling point
C) Melting point
D) Condensation point
Correct Answer:
C) Melting point
Explanation:
The temperature at which a solid changes state to become a liquid is known as the melting point. This is when the solid absorbs enough heat energy to break the intermolecular forces holding its particles in a fixed position, allowing them to move more freely and form a liquid. Options A, B, and D represent other phase change points, such as freezing, boiling, and condensation.
