The graph shows a phase change diagram.
What phase change is taking place as energy is lost at segment BA?
A.
melting
B.
freezing
C.
sublimation
D.
condensation
B. freezing
Bot is correct
The correct answer is B. freezing.
To determine the phase change taking place as energy is lost at segment BA on the phase change diagram, we need to understand the different phases and their corresponding processes.
Segment BA represents a decrease in energy, which implies a loss of heat or cooling. From the given options, the phase change that occurs when cooling takes place is freezing. Freezing is the process in which a substance changes from a liquid phase to a solid phase, typically accompanied by the release of heat.
Therefore, the correct answer is:
B. freezing
