Multiple Choice
Which statement best describes how energy is involved in the process of freezing?
A
Energy is converted into mass during freezing.
B
Energy is released from the substance as it changes from liquid to solid.
C
Energy is absorbed by the substance as it changes from liquid to solid.
D
No energy change occurs during freezing.
Verified step by step guidance1
Understand the phase change involved: freezing is the process where a substance changes from a liquid to a solid.
Recall that during freezing, the particles in the liquid lose energy, which allows them to arrange into a more ordered solid structure.
Recognize that energy must be released to the surroundings for the substance to transition from liquid to solid; this energy release is called the latent heat of fusion.
Note that energy is not absorbed during freezing; instead, it is given off, which is why freezing is an exothermic process.
Conclude that the correct description is that energy is released from the substance as it changes from liquid to solid.
