What is the process called when a solid changes directly into a gas?

Step 1: Understand that matter can exist in different states: solid, liquid, and gas.
Step 2: Know that usually, a solid turns into a liquid before becoming a gas (like ice melting to water and then evaporating).
Step 3: Learn that sublimation is a special process where a solid skips the liquid state and goes directly to gas.
Step 4: An example of sublimation is dry ice (solid carbon dioxide) turning into carbon dioxide gas without becoming liquid first.
