Answer 2

Answer:

The correct statements are only (l) and (11)

Explanation:

A glass filled with ice cubes is kept on a table After some time water drops were observed sticking to the outside of the glass.

This is an example of condensation:
Condensation:

• Due to the change in temperature, the water vapour present in the air undergoes a change in state and gets converted into liquid.
• Condensation proves the presence of water vapour in the atmosphere.
• It is only seen when a cold object is kept in the open and not the other way around.

Therefore, the correct statements are only (l) and (11)
