What happens when water vapor is cooled?
When water vapor in the atmosphere loses heat and cools down, condensation happens. As the water vapor cools down and condenses, it attaches to small particles of dust floating in the atmosphere, forming tiny liquid water droplets. When condensation occurs on the ground, it forms dew.
What is evaporation in simple words?
Evaporation happens when a liquid turns into a gas. It can be easily visualized when rain puddles “disappear” on a hot day or when wet clothes dry in the sun. In these examples, the liquid water is not actually vanishing—it is evaporating into a gas, called water vapor. Evaporation happens on a global scale.

How long would it take for a glass of water to evaporate?
1.2 hours
What is the importance of evaporation in our daily life?
Answer Expert Verified Evaporation is defined as the process of liquid changing into vapor. Importance of evaporation is as follows: Perspiration cools our body through evaporation. The evaporation of liquid from the earth helps to keep the air moist and provides moisture to the clouds.
What is a fact about evaporation?
Evaporation is when a liquid becomes a gas without forming bubbles inside the liquid volume. The water evaporates into water vapor, the gas phase of water. The water vapor mixes with the air. The reverse of evaporation is condensation. When the molecules in a liquid are heated, they move faster.
What are the uses of evaporation?
Evaporation is also used to concentrate liquid foods such as noodles and make condensed milk, the product of a process that removes water from milk. Similarly, pharmaceutical companies use evaporators to remove excess moisture from drugs, thus improving product stability.
What is the principle and application of evaporation?
principle: evaporation is a surface phenomenon. The water molecules at the surface of a container tend to come out. So they gain heat energy from the nearby molecules and evaporates. As a result evaporation takes place. Application: formation of NaCl from sea water.
