Answer 1

through the process of condensation.

Condensation- Condensation is the change of water from its gaseous form (water vapor) into liquid water. Condensation generally occurs in the atmosphere when warm air rises, cools and looses its capacity to hold water vapor. As a result, excess water vapor condenses to form cloud droplets.

Answer 2

${\huge{\underline{\mathcal{\red{Solution}}}}}$

We can change water vapours to water by. the process of condensation or liquefaction . We can change water vapours to water by decreasing it's temperature and increasing its pressure .

Activity :

1. Start Boiling water in a pan .

2. Cover the pan with a plate .

3. You can observe the vapours on the plate

4.You can collect these vapours to convert it into water again
