Which change of state occurs during vaporization?
A
Solid to gas
B
Solid to liquid
C
Liquid to gas
D
Gas to liquid
Verified step by step guidance1
Understand that vaporization is the process where a substance changes from the liquid phase to the gas phase.
Recall the common phase changes: solid to liquid is melting, liquid to solid is freezing, solid to gas is sublimation, and gas to liquid is condensation.
Identify that vaporization specifically refers to the transition from liquid to gas, which includes both evaporation and boiling.
Recognize that the other options (solid to gas, solid to liquid, gas to liquid) correspond to sublimation, melting, and condensation respectively, not vaporization.
Conclude that the correct change of state during vaporization is from liquid to gas.
