Air Composition and Properties Quiz

The process where water vapor in the air changes into liquid water, forming droplets on a cold surface.

Gases like Helium, Neon, Argon, Krypton, and Xenon that rarely react with other elements.

Tiny particles in the air that act as surfaces for water vapor to condense on, leading to rain formation.

The process where plants use sunlight, water, and carbon dioxide to create their own food and release oxygen as a byproduct.

The process where living organisms take in oxygen and release carbon dioxide. It's the opposite of photosynthesis.

A colorless, odorless, and tasteless mixture of gases that primarily consists of nitrogen and oxygen.

Nitrogen comprises 78% of air. It is essential for plant growth, controls combustion, and is used to produce ammonia and fertilizers.

Oxygen makes up 21% of air and is crucial for respiration, supporting the burning process, and various chemical reactions.

Air is a mixture, not a compound. This means its components retain their individual properties. Each gas in air acts and behaves independently.

Water vapor and other trace gases such as carbon dioxide, inert gases, and dust particles make up a small portion of the air, accounting for approximately 1%.

A chemical reaction where a substance rapidly combines with oxygen, producing heat and light.

The gas in air that supports burning.

A colorless, odorless gas used by plants to produce food.

A chemical reaction that uses carbon dioxide to create food for plants.

The air turns milky because carbon dioxide reacts with limewater.

The ancient philosophers believed air was a single element. However, John Mayow discovered in 1674 that air is composed of two main components: an active one (oxygen) and an inactive one (nitrogen).

Oxygen is essential for breathing, combustion, and many chemical reactions. It makes up about 21% of the air we breathe.

Nitrogen, the most abundant gas in the atmosphere (78%), plays a role in plant growth, controlling combustion, and is used to produce fertilizers.

The air we breathe, also known as the atmosphere, protects us from harmful radiation from the sun and helps regulate the Earth's temperature.

The process by which living organisms take in oxygen and use it to produce energy from food, releasing carbon dioxide and water vapor. This energy powers various life activities.

Oxygen is needed for combustion, which is the process of burning fuels. Without oxygen, fires cannot start or continue.

Oxygen is a gas that makes up about one-fifth of the air we breathe.

Carl Wilhelm Scheele, a Swedish chemist, discovered oxygen in 1772 by heating various compounds like potassium nitrate and mercury oxide.

This experiment shows that a burning candle needs oxygen to continue burning. When the oxygen is used up, the flame goes out.

This experiment demonstrates that roughly one-fifth of the air supports burning. Red phosphorus reacts with oxygen, consuming the volume that supports burning.

The red phosphorus reacts with oxygen, consuming about one-fifth of the air in the bell jar. This part of the air is essential for burning.

The activity demonstrates that oxygen is crucial for burning. It is a vital component of air for combustion to take place.

Burning fossil fuels like oil, coal, and natural gas releases carbon dioxide into the atmosphere. This is a major contributor to increased carbon dioxide levels.

As the human population grows, the demand for energy increases, leading to more fossil fuel consumption and consequently, more carbon dioxide release.

Deforestation reduces the number of trees that can absorb carbon dioxide from the air. This results in a greater build-up of carbon dioxide in the atmosphere.

The atmosphere is a blanket of air surrounding Earth, primarily composed of nitrogen and oxygen. It extends up to 1500 kilometers, but most of it is found within 15 kilometers of the Earth's surface.

Photosynthesis is the only known process that directly consumes carbon dioxide from the air. Plants use sunlight, water, and carbon dioxide to produce their food and release oxygen as a byproduct.

Plants use sunlight, water, and carbon dioxide to create food. They release oxygen as a byproduct. It's like a plant's way of making its own snacks.

The process of burning a substance, often with oxygen, to produce heat and light. It's like a fire, releasing energy.

A reddish-brown, flaky substance formed when iron reacts with oxygen and water. It's like a coating on iron that weakens it.

The thin layer of gases that surrounds the Earth. It acts like a blanket, protecting us from harmful radiation and regulating Earth's temperature. It's like a giant bubble protecting our planet.

A colorless and odorless gas that makes up 78% of the air, essential for plant growth and used in industry to make fertilizers.

A colorless and odorless gas that makes up 21% of the air, vital for breathing and burning.

A colorless and odorless gas that makes up about 0.04% of the air, used by plants for photosynthesis and does not support burning.

The industrial process where oxygen, nitrogen, and argon are extracted from air by removing impurities, liquefying the air, and separating gases by fractional distillation.
