What is sublimation?

Sublimation is when something changes from a solid directly into a gas, without becoming a liquid first.

Imagine you have a solid ice cube in your freezer. Normally, it would melt into water (a liquid) and then evaporate into steam (a gas). But with sublimation, the ice cube skips the melting part and turns straight into steam!

Like a Popsicle on a Hot Day

Think of a popsicle that’s left out in the sun. It usually melts into liquid and then dries up. But if it's really cold and dry, like in a freezer with no air, it can skip the melting step entirely, turning from solid straight to gas. That’s sublimation!

A Real-Life Example: Dry Ice

Dry ice is a perfect example of sublimation. It looks like regular ice, but it's super cold (like -78°C!). When you put it on a table, it doesn’t melt, it just fizzes and turns into a misty gas, making spooky clouds around it. No liquid in sight!

So, sublimation is like skipping the middle step of a journey, going straight from solid to gas! Sublimation is when something changes from a solid directly into a gas, without becoming a liquid first.
