b. false

1. fill in the blank(s):

complete the sentence using word droplets, ice or vapor.
in the water cycle, water _______________ in the atmosphere may condense around tiny particles
and form clouds.

1. condensation is not initiated by the formation of molecular clusters.

a. true
b. false

1. which of the following is/are evaporation process?

a. a puddle drying up

Explanation:

Question 1

The process where a gas turns into a liquid is called Condensation. Sublimation is solid to gas, Deposition is gas to solid. So the blank should be filled with Condensation.

Condensation involves gas losing energy (heat) to become liquid, so it releases heat, making it exothermic. Endothermic absorbs heat, temperature - independent is incorrect as temperature affects condensation.

Clouds are made of tiny water droplets or ice crystals, not large masses of water vapor. Water vapor condenses around particles to form cloud droplets. So the statement is false.

Answer:

Condensation
