Change of State: Boiling, Evaporation
Imagine heating a pot of water. As the water heats up, it starts bubbling and steaming. This process is called Boiling.
In this process, the particles gain energy and start moving faster. When their energy becomes strong enough to overcome the attractive forces holding them together, they break free from the liquid, forming water vapor bubbles.
These bubbles rise to the surface and escape into the air, creating visible steam.
Boiling occurs when a liquid changes to a gaseous state at a specific temperature, known as its boiling point. For instance, water boils at 100 ℃.
But did you know water can also turn into a gas without boiling? This process is called evaporation.
It happens at the surface of a liquid when particles absorb enough energy to escape into the air as vapor.
Unlike boiling, evaporation occurs below the boiling point and without bubbling.
It explains why water spilled on the floor gradually disappears and ponds become dry over time.
Both these processes show how energy changes the state of substances from liquid to gas.
