What are volatile substances?

Volatile substances are things that change easily from one state to another, just like how you can turn ice into water with a little heat.

Imagine you have a container full of perfume, when you open it, the smell fills the room almost instantly. That’s because the perfume is a volatile substance; its tiny particles move quickly and escape into the air, letting you sniff it from across the room. It's like when you spill juice on the floor, it spreads out fast, right?

Think of a hot bath. When the water is hot, you can see steam rising. That steam is water turning from liquid to gas because of heat. Volatile substances behave similarly, they turn into gas easily when heated.

Now think about a cold drink on a warm day. The glass gets all sweaty on the outside. That’s because the air around it cools down, and tiny droplets form from water vapor in the air. Volatile substances can also change from gas back to liquid when cooled.

So, volatile substances are like playful little particles that love to move, they turn into gas quickly when heated and become liquid again when cooled.
