What is condensation for kids?

Condensation is the process by which water vapor (water in its gas form) turns into liquid. It happens when molecules of water vapor cool and collect together as liquid water. Water vapor can be found on the outside of cold glasses, the warm side of windows, and in the clouds up in the air.

What is a fact about condensation?

Water vapor condenses into a liquid after making contact with the surface of a cold bottle. Condensation is the process in which gas changes into a liquid when it touches a cooler surface. Condensation is an important part of the water cycle.

What are the 4 types of condensation?

After condensation the water vapour or the moisture in the atmosphere takes one of the following forms — dew, frost, fog and clouds. Condensation takes place when the dew point is lower than the freezing point as well as higher than the freezing point.

What are 2 examples of evaporation?

13 Everyday Life Examples of EvaporationDrying Clothes under The Sun. One of the most common real-life examples of evaporation is drying of clothes under the sun. … Ironing of Clothes. … Cooling Down of Hot Tea and Other Hot Liquids. … Wet Floors. … Melting of Ice Cubes. … Preparation of Common Salt. … Evaporation of Nail Paint Remover. … Drying of Wet Hair.More items…

What causes condensation?

When does condensation occur? Condensation occurs when warm air collides with cold surfaces, or when there’s too much humidity in your home. … When this moisture-packed warm air comes into contact with a chilly surface, it cools down quickly and releases the water, which turns into liquid droplets on the cold surface.

What is the meant by condensation?

Condensation is the change of the physical state of matter from the gas phase into the liquid phase, and is the reverse of vaporization. … It can also be defined as the change in the state of water vapor to liquid water when in contact with a liquid or solid surface or cloud condensation nuclei within the atmosphere.

Is snow an example of condensation?

Rain Falling Down Instead, the condensed droplets get bigger, heavier, and eventually fall to the ground in the form of rain. Other forms of precipitation, such as snow and sleet, are also related to condensation. Snow and sleet are frozen droplets of water.

How do you speak condensation?

Break ‘condensation’ down into sounds: [KON] + [DEN] + [SAY] + [SHUHN] – say it out loud and exaggerate the sounds until you can consistently produce them. Record yourself saying ‘condensation’ in full sentences, then watch yourself and listen. You’ll be able to mark your mistakes quite easily.

What happens 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.

What is a real life example of sublimation?

Examples of Sublimation The best example of sublimation is dry ice which is a frozen form of carbon dioxide. When dry ice gets exposed to air, dry ice directly changes its phase from solid-state to gaseous state which is visible as fog. Frozen carbon dioxide in its gaseous state is more stable than in its solid-state.

Is Steam an example of condensation?

Condensation is the process by which water vapor in the air is changed into liquid water. … The steam, another form of water vapor, and bubbles you see in the boiling pot of water are evidence of the liquid being changed into gas.

What is condensation and its types?

Condensation: Dew, Fog, and Clouds. CHAPTER7. Condensation: Dew, Fog, and Clouds. Dew: the water droplets formed by condensation of water vapor on a relatively cold surface of an object. It forms when the temperature of an object drops below the dew point temperature.

What is condensation in chemistry class 9?

Condensation is the process through which the physical state of matter changes from the gaseous phase into the liquid phase. … When the water in the air comes in contact with a cold surface, it condenses to form water droplets. The opposite of condensation is evaporation reaction.

What is condensation short answer?

Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor. Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water. Dew Point.

What is condensation give example?

Condensation is a physical change in the state of matter of a substance. … Examples of Condensation: 1. Having a cold soda on a hot day, the can “sweats.” Water molecules in the air as a vapor hit the colder surface of the can and turn into liquid water.

What is sublimation class 9th?

The Changing of a solid directly into vapours on heating,and of vapours into solid on cooling is called as sublimation. The solid substance which undergoes sublimation is called sublime. The solid obtained by cooling the vapours of the solid called a sublimate. For Ex:camphor,Iodine,Ammonium Chloride,Naphthalene etc.

What is melting point Class 9?

The melting point is usually defined as the point at which materials changes from a solid to a liquid. The temperature at which solid changes its state to liquid at atmospheric pressure is called the melting point of that liquid. This is the point at which both liquid and solid phase exists at equilibrium.
