검증된 단계별 안내1
Understand the phase changes between states of matter: solid, liquid, and gas.
Identify that melting is the process where a solid absorbs heat and changes into a liquid.
Recall that condensation is the change from gas to liquid, not solid to liquid.
Recognize that freezing is the process where a liquid changes into a solid, the opposite of melting.
Know that sublimation is the direct transition from solid to gas, bypassing the liquid phase.
