0 Comments
Verified step by step guidance1
Understand the phase changes between states of matter: solid, liquid, and gas.
Recall that melting is the process where a solid changes into a liquid.
Know that condensation is the process where a gas changes into a liquid.
Recognize that sublimation is the process where a solid changes directly into a gas without passing through the liquid phase.
Identify that the reverse of sublimation, where a gas changes directly into a solid without becoming a liquid first, is called deposition.
