Explanation:

Evaporation is a process of liquid turning into its gaseous form. It happens when the liquid molecules gain enough energy to break their bonds and escape into the air as a gas. The most common example of evaporation is the drying of wet clothes.

When wet clothes are exposed to air, the water molecules in them start to gain energy from the surrounding environment. This energy causes the water molecules to move faster and break their bonds with each other. As a result, the water molecules escape into the air as water vapor. This process of water turning into water vapor is called evaporation.

Factors affecting evaporation:

The rate of evaporation depends on several factors, such as:

1. Temperature: Higher temperature means more energy is available to the liquid molecules, which results in faster evaporation.

2. Humidity: The amount of water vapor in the air affects the rate of evaporation. Higher humidity levels mean that there is already a lot of water vapor in the air, which slows down the evaporation process.

3. Surface area: More surface area means more evaporation, as there are more molecules exposed to the air.

4. Wind speed: Wind can carry away the water vapor from the surface, which results in faster evaporation.

Uses of evaporation:

Evaporation has several practical uses, such as:

1. Drying clothes: As mentioned earlier, evaporation is the process that dries wet clothes.

2. Producing salt: Salt can be produced from seawater through the process of evaporation.

3. Cooling systems: Evaporative cooling systems use the principle of evaporation to cool down the air.

Conclusion:

Evaporation is a natural process that occurs when a liquid turns into its gaseous form. It happens when the liquid molecules gain enough energy to break their bonds and escape into the air as a gas. The most common example of evaporation is the drying of wet clothes.

Option C s the right one. as all others will end in some tme. but a leaky toilet keep wasting water until fixed. the a,c and d options are water is used. but leakage is 100%waste.
