Sublimation happens when a solid turns DIRECTLY into a gas without becoming a liquid first!
It’s like skipping the liquid step.
🧊 EXAMPLES OF SUBLIMATION 🧊
1️⃣ Dry Ice (Frozen Carbon Dioxide):
Dry ice doesn’t melt into water.
Instead, it CHANGES STRAIGHT INTO A FOGGY GAS!
(You’ve probably seen this in science shows or at a marriage .)
2️⃣ Snow on a Freezing Day:
When it’s super cold, snow can DISAPPEAR INTO THE AIR without melting.
This happens when the snow turns straight into water vapor (gas)!
🔬 HOW DOES IT WORK?
The solid gets energy (from heat or sunlight).
It skips the liquid phase and BECOMES GAS IMMEDIATELY.
This often happens in low pressure or special conditions.
🎩 IT’S LIKE A NATURE MAGIC TRICK!
From solid 👉 to gas... no liquid needed!
