Question

Phase $A$ $\to$ Phase $B$ is a process of __________.

• A. sublimation
• B. deposition
• C. vaporization
• D. condensation
• E. melting

Answer 1

The correct option is E melting

A typical diagram of a phase change process is shown in the figure. Here, the $Y-axis$ is pressure whereas the $X-axis$ is temperature. It can be clearly seen that A is a solid region whereas B is the liquid region. Since a solid can be converted to a liquid via melting, E is the correct answer
