Evaporation is the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor.
Why does evaporation happen for kids?
Evaporation happens when a liquid is heated. The heat gives the liquid’s molecules more energy. This energy causes the molecules to move faster. If they gain enough energy, the molecules near the surface break away.
What causes water to evaporate?
In the water cycle, evaporation occurs when sunlight warms the surface of the water. The heat from the sun makes the water molecules move faster and faster, until they move so fast they escape as a gas. Once evaporated, a molecule of water vapor spends about ten days in the air.
What are 5 example of evaporation?
Wet clothes drying in sun. Evaporation of perspiration from body. Drying of a mopped floor. Drying of wet hair.
What is the meaning of evaporation for kids?
Kids Definition of evaporate. 1 : to change into vapor The liquid evaporated quickly. 2 : to remove some of the water from something (as by heating) evaporate milk. 3 : to disappear without being seen to go Their savings quickly evaporated.
How can evaporation be used to keep things cool?
When water evaporates, it changes from a liquid to a gas. The gas carries away heat with it, helping to remove heat from your skin. Not only can evaporation cool down your body, it can also cool down other things, such as chocolate.
What are facts about evaporation?
Evaporation is a geologic process that concentrates the ion solute residues in the ocean basins. At a fundamental level, evaporation is the transition of the molecule of a liquid from the liquid state to the gaseous state by diffusion from the surface of the liquid.
How do you Calculate evaporation rate?
Answer Wiki. 1 Answer. the rate of evaporation is calculated by the weight of initial liquid and weight of liquid after some time. for eg: if in 1 hr the weight of liq. is decreased 100 gm then the rate of evaporation is 100 gm per hour.
