A blanket of gases surrounding the planet is known as

atmosphere

A greenhouse gas that absorbs energy and maintains the earth's temperature is

carbon dioxide

A method that is mainly used in separating the components of crude oil is known as

fractional distillation

A reaction in which oxygen is used up for the production of thermal and light energy is known as

combustion

A thin layer that is held in place by gravity and provides us with oxygen is known as

atmosphere

Air is a mixture that makes up the

atmosphere

Air is important because it is the prime cause of life on

Earth

Air is important on earth because it has necessary components essential for the life of

plants, animals and other organisms

Air present in 100cm3 of water is about

2cm3

Air solubility of water is defined as the ability of air to be dissolved in

water

An odorless, invisible gas that makes about 20%-22% of the earth's atmosphere is known as

oxygen

As the temperature of the air increases, there is an increases in the capacity of

water vapor

Both gas and liquids are fluids. Fluids are substances which don't have fixed

shape

Breathing is a process that refers to the inhaling and exhaling of

air

Combustion cannot take place without

air

Earth's atmosphere extends hundreds of kilometers above the

surface

Exhaled air contains 16% oxygen and about 4% of carbon dioxide, the rest of 80% is

nitrogen

Fish exchange oxygen and carbon dioxide through gills in

water

Fractional distillation consists of

two steps

Human respiratory system contains respiratory tract and

lungs

In desert areas, the water vapor content is

low

Nitrogen is obtained from the fractional distillation of liquefied air at about

186 ?C

In fish, respiration takes place through

gills

In humid areas, the water vapor content is

higher

In leaves, gaseous exchange takes place through tiny pores under the leaves known as

stomata

In respiration glucose and oxygen combine together to form

carbon dioxide & water

In respiration, living organisms take in oxygen and give out

carbon dioxide

Intake of carbon dioxide and giving out of oxygen is the only process named

photosynthesis

Iron rusts when it comes in contact with

oxygen & water

Nitrogen gas and nitrogen compounds, both have very important

industrial uses

On cooling, a liquid will be changed into

solid

Other than nitrogen and oxygen, the composition of the rest of the gases is about

Oxidation is accompanied by

heat & light

Oxygen is used in the manufacture of

metal

People having respiratory problems like asthma, are dosed medically with

oxygen

Photosynthesis is a process in which carbon dioxide and water combine to form

carbohydrates

Photosynthesis occurs during the

day time

Respiration takes place at/in

night

Respiratory system contains organs necessary for the process of

respiration

Rust is actually

iron oxide

Sunlight is absorbed by chlorophyll in leaves, while the gaseous exchange takes place through

leaf stomata

The atmosphere is an important part for life on

Earth

The breathing system of plants is present in

leaves

The chemical formula of ozone is

The condensation point of nitrogen gas is

-196 ?C

The condensation point of oxygen gas is

-183 ?C

The first step of fractional distillation of liquefied air is to bring the air to a very

low temperature

The fractional distillation is a process in which liquids evaporate at

different temperature

The layer that blocks the ultraviolet (UV) rays from the sun is

ozone layer

The left over gas after the process of combustion is generally

nitrogen

The liquefied air is put into an apparatus known as

fractionating column

The main constituent in air is

nitrogen

The major use of nitrogen is production of

ammonia

The mixture important for human life and combustion is

air

The moisture capacity of air is called

humidity

The most abundant element is oxygen within the

Earth's crust

The percentage composition of carbon dioxide in exhaled air is

The percentage composition of nitrogen in air is

78%

The percentage composition of oxygen in air is

21%

The percentage composition of oxygen in exhaled air is

16%

The process in which energy is released by the combination of glucose and oxygen is known as

respiration

The process of burning under the presence of oxygen is known as

combustion

The process of trapping some of the heat from the sun to maintain the life on earth is known as

greenhouse effect

The second step of fractional distillation is heating the mixture so that components evaporate at th

boiling point

The sphere that prevent the ultraviolet rays from sun is known as

atmosphere

The state that fills the volume of its container is

gas

There is no boundary between atmosphere and space, so the density of atmosphere decreases with

increasing altitude

To perform fractional distillation of air, it must be liquefied and then purified to remove

dust

Water vapor is less dense than
