What are phase transitions?

Phase transitions are when something changes from one state to another, like ice melting into water.

Imagine you have a cup of juice. If it’s in the fridge, it might be solid, like frozen juice. If you take it out and let it sit on the table, it becomes liquid, just regular juice. If you heat it up more, maybe it starts to bubble and turn into gas, like steam rising from your cup. These are all different states of matter.

Think about a blanket. When it’s cold, the blanket is tight and stiff, like solid. As you warm up, the blanket gets looser and easier to move, like liquid. If it's really hot, the blanket might even feel like it's floating in the air, like gas.

When something changes from one state to another, that’s a phase transition. It happens because the tiny particles inside the juice or blanket are moving faster or slower, depending on the temperature, just like you when you're sleepy or full of energy!
