The wet clothes dry due to evaporation of water present in them. Thus the fast moving particles (or molecules) of a liquid are constantly escaping from the liquid to form vapor (or gas).

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

$\large\sf\underline{Question - no. 1}$

How are clouds formed ?

$\large\fbox\red{Answer ࿐}$

The process of evaporation followed by condensation causes the formation of clouds. On reaching a certain height, water vapour present in air condenses to form tiny droplets of water. These water droplets collect to form clouds that float in air.

Define Evaporation.

$\large\fbox\red{Answer ࿐}$

Evaporation is defined as the process of a liquid changing into a gas.

An example of evaporation is water turning into steam.

$\large\sf\underline{Question - no. 3}$

Define condensation.

$\large\fbox\red{Answer ࿐}$

Condensation is a physical change in the state of matter of a substance.

Examples of Condensation : Having a cold soda on a hot day, the can "sweats." Water molecules in the air as a vapor hit the colder surface of the can and turn into liquid water
