Is a puddle evaporating a physical change?
The evaporation of water is a physical change. When water evaporates, it changes from the liquid state to the gas state, but it is still water; it has not changed into any other substance.
What happens to the molecules when the water is gone?
When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. Evaporation is a very important part of the water cycle.
Why does a puddle of water evaporate?
Key Concepts. 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.
How does a puddle disappear?
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.
Which process explains why puddles of water disappear after a rainstorm ends?
Which of the following changes when water evaporates?
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.
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.
Why do liquids evaporate at different rates?
This is because different molecules require varying quantities of energy to evaporate. Heavier molecules need more energy than lighter molecules, as more mass requires more power. Similarly, the density of a given liquid will affect the rate at which liquids can heat up, and therefore evaporate.
Why does a puddle disappear?
When water evaporates from a puddle What happens to the temperature of the puddle explain?

How often should you record the evaporation of a puddle?
(Note: Explain that he should try to record the information as accurately as possible. If the puddle on the sidewalk is smaller, the illustration on the paper should look smaller, too.) Repeat at hourly intervals until the puddle has disappeared.
Why does water dry up in a puddle?
The reason why the puddle dries up is because the motion of the water is not uniform, there are places and times – especially along the surface where the energy of the water molecule is high enough to break the bonds (I think its called an “electrostatic force”).
How to explain puddle science to your child?
Have your child look over the information on his chart, and explain what he notices about the information he has collected. In general, he should notice that over time, the puddle got smaller and smaller, but basically stayed the same shape.
