What conditions are required for evaporation to occur?

What conditions are required for evaporation to occur?

Heat (energy) is necessary for evaporation to occur. Energy is used to break the bonds that hold water molecules together, which is why water easily evaporates at the boiling point (212° F, 100° C) but evaporates much more slowly at the freezing point.

What happens when water vapor condenses in the atmosphere?

Condensation is the process by which water vapor in the air is changed into liquid water. As condensation occurs and liquid water forms from the vapor, the water molecules become more organized and heat is released into the atmosphere as a result.

What process is responsible for adding water vapor into the atmosphere?

And water vapor gets into the atmosphere from plants by a process called transpiration. Because air is cooler at higher altitude in the troposphere, water vapor cools as it rises high in the atmosphere and transforms into water droplets by a process called condensation.

What are the three main processes that must occur for water to move through the atmosphere?

Water and the atmosphere Water enters the atmosphere through evaporation, transpiration, excretion and sublimation: Transpiration is the loss of water from plants (via their leaves). Animals excrete water by respiration and by passing urine.

What is the liquid state of water?

Liquid water is wet and fluid. This is the form of water with which we are most familiar. We use liquid water in many ways, including washing and drinking. Water as a gas—vapor is always present in the air around us.

How can you change water to ice?

Water can exist as a solid (ice), liquid (water) or gas (vapour or gas). Adding heat can cause ice (a solid) to melt to form water (a liquid). Removing heat causes water (a liquid) to freeze to form ice (a solid). When water changes to a solid or a gas, we say it changes to a different state of matter.

How is evaporation dependent on temperature?

Since the kinetic energy of a molecule is proportional to its temperature, evaporation proceeds more quickly at higher temperatures. As the faster-moving molecules escape, the remaining molecules have lower average kinetic energy, and the temperature of the liquid decreases.

How does rate of evaporation depends on wind speed?

The speed at which air flows over the surface of water affects the rate at which the water evaporates. As the wind blows, it sweeps away airborne water particles that are in the air. The humidity of the air in the region of this evaporation is reduced, which allows more water molecules to dissipate into the air.
