Answer 1

Explanation:

Evaporation is a type of vaporization that refers to the process of a liquid changing into gas.
The process of the liquid changing into vapour even below its boiling point is called evaporation.
The factors affecting evaporation are explained below:

Factors	Explanation
Humidity of air	Humidity is the amount of water vapour present in the air. The air around us cannot hold more than a definite amount of water vapour at a given temperature. If the humidity increases, the rate of evaporation decreases.
Wind speed	The rate of evaporation of liquid increases with increasing wind speed. When it increases, the particles of water vapour moves away from the wind, decreasing the amount of water vapour in the surroundings.
The surface area of the liquid	The rate of evaporation increase by increasing the surface area of the liquid. This is because of the more exposure to the water in the air.
Temperature	The rate of evaporation increases by increasing the temperature of the liquid. The rate of evaporation of a liquid can be increased by heating it. It becomes maximum at its boiling point.

Thus, the process of evaporation will be the slowest when both surface area and temperature decreases.
