$\tt\large{\blue{Answer1:-}}$

The particles of matter are very, very small. The particles of matter have space between them. The particles of matter are constantly moving. The particles of matter attract each other.

$\tt\large{\pink{Answer2:-}}$

Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. The surrounding gas must not be saturated with the evaporating substance. When the molecules of the liquid collide, they transfer energy to each other based on how they collide with each other.

$\tt\large{\green{Answer3:-}}$

Factors That Affect the Rate of Evaporation are listed below⇩

✽Temperature of the liquid. A cup of hot water will evaporate more quickly than a cup of cold water.

✽Exposed surface area of the liquid.

✽Presence or absence of other substances in the liquid.

✽Air movement.

✽Concentration of the evaporating substance in the air.
