What is happening?

• The “steam” from the kettle is water in the gas state.
• When this warm water vapour touches the cold window, it cools down and turns back into liquid water, forming tiny droplets.

Name of the change of state

• Gas → Liquid is called condensation.
• So, when steam hits a cold window and makes droplets, the process is condensation.
