When liquid bromine is cooled to form a solid, which phase transition occurs?
A
Sublimation
B
Freezing
C
Melting
D
Condensation
Verified step by step guidance1
Identify the initial and final states of bromine in the problem: it starts as a liquid and changes to a solid.
Recall the definitions of phase transitions: Sublimation is solid to gas, Melting is solid to liquid, Condensation is gas to liquid, and Freezing is liquid to solid.
Match the phase transition to the change from liquid to solid, which corresponds to freezing.
Understand that freezing involves the removal of heat from the liquid, causing molecules to slow down and arrange into a solid structure.
Conclude that the correct phase transition when liquid bromine cools to form a solid is freezing.
