This task is about condensation and evaporation of water.

Evaporation = When liquid water is warmed, e.g., by the sun, it turns into steam or vapour (a gas) and goes into the air.
Condensation = When air touches a cold object, the water droplets in the air turn to water on the cold object.

The table below has examples of evaporation, condensation, or neither.

Put a circle around evaporation, condensation, or neither, to show what each example is.
