Question

Relative humidity must be at least 100% before cloud droplets can form.

True

False

Answer 1

False

Step-by-step explanation:

• The relative humidity is the ratio of the water vapor to vapor pressure at a given temperature, the same amount of water vapor leads to the higher relative humidity in cooler air than in warm air i.e dew point.

• As clouds are composed of water droplets particularly ice crystals. As typical when the clouds are formed in a cool air the temperature equals the dew point. Which is 100% humidity resulting in condensation that produces clouds.

• Over the oceans, the ability to dissolve the salt and the ability to hold on molecules of water is called a Solute effect. This allows the clouds to form at a humidity of less than 100%. Nucleation is an initial part of a cloud droplet around any type of particle.
