Question

The process due to which a solid changes into liquid state on the absorption of the heat energy is called:

• A. Melting
• B. Fusion
• C. Liquation
• D. Either (A) or (B)

Answer 1

The correct option is D

Either (A) or (B)

D: Either (A) or (B)

Explanation for Correct answer:

1. Melting: It is a process of conversion of a solid into a liquid state by absorbing heat energy.
2. For example: Ice converts into the water by absorbing heat energy.
3. Fusion: The process due to which solid changes into the liquid state at some fixed temperature by the absorption of heat is know as fusion.
4. Fusion and melting both are the same thing.

Explanation for incorrect option:

C: Liquation: It is a separation technique for the constituents of ore, a metal, or an alloy by partial melting.

Hence, the correct answer is an option (D): Either (A) or (B)
