Evaporation is defined as the process of a liquid changing into a gas. An example of evaporation is
water turning into steam
. … Evaporation takes place at the surface of a liquid, where molecules with the highest kinetic energy are able to escape.
What is evaporation give two examples?
Drying clothes under the sun: water is removed from the clothes as water droplets get evaporated due to heat of the sun. 2.
Drying up of water and potholes from streets
: water gets evaporated from the potholes and puddles due to rain as it gets evaporated due to heat of the sun.
What are 5 examples of evaporation?
- Drying Clothes under The Sun.
- Ironing of Clothes.
- Melting of Ice Cubes.
- Preparation of Common Salt.
- Evaporation of Nail Paint Remover.
- Drying of Wet Hair.
- Drying up of Different Water Bodies.
- Evaporation of Sweat from Body.
What is evaporation give three examples?
Evaporation is defined as the process in which the state of water from liquid to gaseous or to vapour state takes place. …
The melting of an ice cube
is an example of evaporation. Evaporation of acetone which is used for removing nail paint is another everyday example of evaporation.
What is a good example of evaporation?
Evaporation happens when liquids change into gas. It is part of the water cycle. One common example of evaporation is
the steam rising from a hot cup of coffee
. This heat rising out of the cup helps the coffee to cool down.
Is boiling water an example of evaporation?
Evaporation takes place only at the surface of a liquid, whereas
boiling may occur throughout the liquid
. … For example, a puddle of water will evaporate on a cold day, though the rate of evaporation will be slower than it would be on a warm day. In contrast, boiling only occurs at the boiling point of the liquid.
What is difference between evaporation and condensation?
Condensation is
the change from a vapor to a condensed state
(solid or liquid). Evaporation is the change of a liquid to a gas. Microscopic view of a gas. … Example: Water vapor condenses and forms liquid water (sweat) on the outside of a cold glass or can.
What is evaporation explain?
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.
Which of the following shows the best example of evaporation?
- Hot tea getting cold.
- Wet clothes drying in sun.
- Evaporation of perspiration from body.
- Drying of a mopped floor.
- Drying of wet hair.
- Drying up of lakes and rivers.
What is evaporation Class 9?
Answer: Evaporation is the process in which a liquid state of matter (water) is converted into a gaseous state of matter (vapour). In general terms, evaporation is defined as the
process in which the liquid state is converted into gas
. This process requires heat energy.
What is the most important use of evaporation?
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. In industries evaporation is used as a treatment of separation.
Why do we use evaporation?
Evaporation is
used to separate a soluble solid from a liquid
. For example, copper sulfate is soluble in water – its crystals dissolve in water to form copper sulfate solution. During evaporation, the water evaporates away leaving solid copper sulfate crystals behind.
What is evaporation and how does it happen?
Evaporation happens
when a liquid substance becomes a gas
. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. … Heat from the sun, or solar energy, powers the evaporation process.
What’s an example of condensation?
Condensation is the process of water vapor turning back into liquid water, with the best example being those
big, fluffy clouds floating over your head
. And when the water droplets in clouds combine, they become heavy enough to form raindrops to rain down onto your head.
How do you explain evaporation to a child?
Evaporation is
when a liquid becomes a gas without forming bubbles inside the liquid volume
. If bubbles are formed we are talking instead about “boiling”. For example, water left in a bowl will slowly disappear. The water evaporates into water vapor, the gas phase of water.
What is needed for evaporation process?
Answer:
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.
