Which of the following best describes the process of melting in a phase diagram?
A
The transition from liquid to gas as temperature increases at constant pressure.
B
The transition from solid to liquid as temperature increases at constant pressure.
C
The transition from gas to solid as temperature decreases at constant pressure.
D
The transition from liquid to solid as temperature decreases at constant pressure.
Verified step by step guidance1
Understand that a phase diagram shows the states of matter (solid, liquid, gas) of a substance at different temperatures and pressures.
Identify that melting is the process where a solid turns into a liquid, which occurs when temperature increases at constant pressure.
Recognize that the transition from liquid to gas is called vaporization or boiling, not melting.
Note that the transition from gas to solid is called deposition, and from liquid to solid is called freezing or solidification.
Conclude that melting specifically refers to the transition from solid to liquid as temperature increases at constant pressure.
