What happens to a puddle on a hot day?
Evaporation is a key step in the water cycle. 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. When liquid water reaches a low enough temperature, it freezes and becomes a solid—ice.
What will eventually happen to the water in a puddle?
When a puddle dries up, tiny particles of water break away from the liquid in the puddle and go into the air. The tiny water particles are called water molecules. Water on the ground goes into the air, becomes part of a cloud, and comes back down to Earth as rain.
Is water evaporating from a puddle caused by heat?
This energy exists in the form of heat. Evaporation happens when a liquid is heated. For example, as the sun heats water in a puddle, the puddle slowly shrinks. The water seems to disappear, but it actually moves into the air as a gas called water vapor.
When water evaporates from a puddle What happens to the temperature of the puddle?
Liquid molecules that have this certain threshold kinetic energy escape the surface and become vapor. As a result, the liquid molecules that remain now have a lower average kinetic energy. As evaporation occurs, the temperature of the remaining liquid decreases.
What happens to water if it is left in an open container overnight?
Evaporation may occur when water is left in an open container. The liquid water turns to a vapor and the volume of liquid may decrease over a period of time. This occurs because the molecules at the surface of the water escape into the atmosphere, a liquid to gas state.
Can a house well run dry?
When a well “runs dry” it doesn’t mean that the well will never produce water again. Aquifers can recharge through a combination of more precipitation and less pumps pulling water out of that aquifer. Sometimes wells can run dry permanently, but that is quite uncommon.
What happens when a liquid is heated very short answer?
When a liquid is heated, it turns to its gaseous state (or converted into vapour).
What happen when a liquid is heated Class 9?
What happens when a liquid is heated? As a liquid is heated, its temperature increases. As its temperature increases, the molecules of the liquid gain energy and their kinetic energy increases. This produces a pressure above the liquid equal to the atmospheric pressure and the liquid starts boiling.
