1. explain as the day gets warmer, the water droplets on a spider web are no longer seen. why?

what is the process of condensation?
on a hot day in the summer, a glass of ice water m look like it is sweating. the water drops on the out - side of the glass have formed because of condensatio condensation is the change of state from a gas to a uid. the water vapor in the air (sometimes called hum ity) hits the cold glass. the particles of water vapor lo energy and change into the liquid state.
condensation happens when a gas is cooled. when the gas cools, the particles lose energy, move slower, a have a greater attraction for each other. the particles begin to clump together. condensation and evaporatio are the opposites of each other. when condensation ha pens, the particles of gas lose energy and move more slowly. for evaporation to occur, the particles of a liqu must gain energy, and move faster.
the condensation point of a substance is the tem - perature at which a gas becomes a liquid. under most conditions, the condensation point of a substance is th same temperature as the boiling point of the substance condensation can occur when the temperature of a su face is below the condensation point of the gas.
for example, water drops form a haze on a bathroor mirror when you take a shower. the water drops con - dense from the water vapor in the air. the mirror is at a temperature well below water vapors condensation point, 100°c.
take a close look at the spider web in the figure belo notice the beads of water that have formed on it. this happens because water vapor (a gas) has condensed to form liquid water.
beads of water form when water vapor in the air contacts a cool surface, such as this spider web.

Explanation:

Answer:

(9) Water from a lake evaporates, turning into water vapor. The water - vapor rises into the atmosphere. As it rises, it cools. When the water vapor cools enough, it condenses around tiny particles (nuclei) in the air to form tiny water droplets or ice crystals, which together make up a cloud.
(10) Evaporation
(11) As the day gets warmer, the temperature rises above the dew - point temperature. The water droplets on the spider web gain energy and evaporate, turning back into water vapor, so they are no longer seen.
