What causes rain Class 9?

What causes rain Class 9?

Rain is produced by two natural processes, i.e., evaporation and condensation. The water from water bodies evaporates into the air and gets condensed in the form of tiny droplets. Enormous droplets of water appear in the form of clouds. When the droplets become big and heavy, they fall down in the form of rain.

How the rain is formed?

Rain is liquid precipitation: water falling from the sky. Raindrops fall to Earth when clouds become saturated, or filled, with water droplets. Millions of water droplets bump into each other as they gather in a cloud. When a small water droplet bumps into a bigger one, it condenses, or combines, with the larger one.

What are effects of rain?

Heavy rainfall can lead to numerous hazards, for example: flooding, including risk to human life, damage to buildings and infrastructure, and loss of crops and livestock. landslides, which can threaten human life, disrupt transport and communications, and cause damage to buildings and infrastructure.

What type of air causes rainfall?

Warm air can pick up moisture from water sources (seas, lakes etc.); Warm air cools as it rises; Water vapour condenses to form clouds; Rainfall may occur.

What are three causes of precipitation?

Causes of Precipitation: Convection, Orographic Uplift & Frontal Uplift.

What causes rainfall or snowfall?

When condensation takes place below 0° C and precipitation occurs in the form of flakes causes snowfall. If the humidity below the cloud base is low, the crystals may evaporate after leaving the cloud and so never reach the ground.

What are the 2 reasons that precipitation occurs?

Precipitation forms in the clouds when water vapor condenses into bigger and bigger droplets of water. When the drops are heavy enough, they fall to the Earth. If a cloud is colder, like it would be at higher altitudes, the water droplets may freeze to form ice.

Is snow a condensate?

Rain Falling Down Rain occurs when too much water condenses around atmospheric dust particles for the water to remain in the sky in the form of clouds. Other forms of precipitation, such as snow and sleet, are also related to condensation.

What are 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.

What is a good example of condensation?

Common examples of condensation are: dew forming on grass in the early morning, eye glasses fogging up when you enter a warm building on a cold winter day, or water drops forming on a glass holding a cold drink on a hot summer day. Condensation occurs when water droplets form due to cooling air.

What happens during condensation?

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.

How do you show condensation?

Fill a cup approximately two-thirds full of hot water. Take another cup, flip it upside down, and place it on top of the cup with hot water. Then place an ice cube on top of the upside down cup. Condensation will begin to form at the top of the upside down cup, just like a cloud.

What is condensation explain with example?

Condensation is the process through which the physical state of matter changes from the gaseous phase into the liquid phase. For example, condensation occurs when water vapour (gaseous form) in the air changes into liquid water when it comes in contact with a cooler surface.

Can we create water?

Is it possible to make water? Theoretically, it is possible. You would need to combine two moles of hydrogen gas and one mole of oxygen gas to turn them into water. However, you need activation energy to join them together and start the reaction.

What is water generation?

Atmospheric water generation (AWG) uses technology to produce potable water from surrounding air. This provides the potential to expand water availability during shortages, contamination events, and other issues that can interrupt drinking water services.

Can you drink water from a dehumidifier?

The water the dehumidifier collects is actually very clean water; comparable to distilled water. But if the water sits around in the tank, it can provide a hospitable medium for the growth of bacteria and molds making it unfit for drinking.

How much water should my dehumidifier collect?

Although the amount of water collected by a dehumidifier largely depends on its size and capacity to collect water, most small domestic dehumidifiers are capable of collecting 10 to 20 liters of water per day and larger models can even collect up to 50 liters of water per day.

Can dogs drink water from a dehumidifier?

Would it be safe to use the water I take from my dehumidifier and give it to my pets? No. The typical collection tank from a residential dehumidifier is not a safe source of potable water, and certainly isn’t up to the quality of commercially-distilled water.

What can I do with water from dehumidifier?

Let’s just say the dehumidifier was not designed to collect clean, distilled water. If you are diligent, emptying the water once a day or as often as it fills up, the water can be used wherever distilled water can, such as in: Small appliances, like hot water urns or steam irons.

How pure is deionized water?

Deionized (DI) water is water that has been treated to remove all ions – typically, that means all of the dissolved mineral salts. Because water has a lower boiling point than most contaminants (including minerals), they are left behind when the water turns into steam. The resulting water is, therefore, very pure.

How do you clean a dehumidifier?

How to Clean a Dehumidifier

1. Turn off and unplug your machine. Bring the dehumidifier away from the electrical source to ensure it is safe to handle its parts.
2. Wipe down the dehumidifier.
3. Reservoir cleaning.
4. Wash the dehumidifier filter.
5. Vacuum out the machine.

Will a dehumidifier kill plants?

Plants need moisture from the soil or air to complete the photosynthesis equation. However, even those with high humidity levels that regularly use a dehumidifier, won’t kill their plants – providing they’re the right plants; cared for, watered, and shown some indirect sunlight from time to time.

Do plants need a dehumidifier?

Unfortunately, a large number of houseplants do not grow very well in drier environments. Because of this, it is possible dehumidifiers are bad for houseplants Choosing plants that are more tolerant of drier air is a good way to go, but you probably want to keep the houseplants that you already have.

Do air plants absorb moisture?

However, it absorbs most of its moisture from the air, making it great for absorbing humidity. This is because it is an epiphyte and does not live in soil. This little plant is also called air plant because of its epiphytic nature and ability to live in a soilless situation and still feed and water itself.

Can plants remove Mould?

However, plants can also help remove mould from rooms by releasing phytochemicals that suppress mould spores and bacteria. In fact, rooms with plants have 40 to 60 percent fewer mould spores and bacteria. Bathrooms, kitchens and rooms that suffer with humidity, damp, mildew or mould could benefit from houseplants.
