Answer 1

The water in the kettle is boiling.
As it boils, it changes into steam.
This process is known as vaporisation.
If you hold a cold metal plate near the spout of the kettle, the steam condenses into droplets of water. The water can then be collected in a beaker. Hence, this is an example of reversible change.
