What will most likely happen if the relative humidity reaches 100% and the air temperature is very high??

Moisture will increase. Then the air temperature will increase and get warmer. Precipitation is likely to occur.

Hope it helps!! :)

When relative humidity reaches 100 percent or is saturated, moisture will condense, meaning the water vapor changes to liquid vapor. As air temperature increases (or becomes warmer), more water remains in a gas phase.

By water evaporation from the leaves is created a negative pressure at the top of the tree that promotes the ascension  of the water through channels that are called xylem. there are also two molecule forces that are involved: the intra-water molecules cohesion (water molecules stick to each other) and the adhesion when the water molecules stick to the channels they are running in. this is what enables water to go from the roots to the top of a tall tree.
