Sublimation is a really interesting process. It's when a solid changes straight into a gas without becoming a liquid first. This happens because tiny particles in the solid get enough energy to break free and float away into the air.

Common Examples:

• Dry Ice: Dry ice is frozen carbon dioxide. When you leave it out at room temperature, it turns into gas, which looks like a fog. This fog is often used in parties and shows.
• Snow in the Sun: On a sunny day, you might notice that snow seems to disappear. It doesn’t melt into water first. Instead, it changes directly into water vapor, which is a gas.

Everyday Observations:

• Have you ever seen ice cubes getting smaller in the freezer? That’s also sublimation happening!

Learning about sublimation helps us see the different ways that things can change from one form to another in our everyday lives.
