What is smoke Short answer
When something burns, gas and tiny pieces of solid material are released into the air as smoke.
What is dust and smoke for Class 6
Dust and smoke are both air pollutants that are made up of small, airborne particles that are suspended freely in the atmosphere.
What is smoke and dust
Dust is a mixture of soil, cosmic dust, pollen, textile fibers, hair, and dead skin, whereas smoke is a mixture of fine particles created when burning wood and other organic matter in the presence of gases, including water vapour, carbon dioxide, carbon monoxide, trace minerals, benzene, etc.
What kind of pollution is smoke
Particle pollution is a major component of wildfire smoke and the main public health concern. It is made up of a mixture of gaseous pollutants, such as carbon monoxide, hazardous air pollutants (HAPs), such as polycyclic aromatic hydrocarbons (PAHs), water vapor, and other pollutants.
What is smoke how it is produced
Smoke is a collection of these minute unburned particles that result from incomplete combustion, which happens when there is not enough oxygen to completely burn the fuel. In complete combustion, everything is burned, leaving only water and carbon dioxide.
What is respiration class 6th
Internal respiration, also known as cellular respiration, is the process by which food is broken down into carbon dioxide and water in the presence of oxygen to produce energy. External respiration, also known as breathing, is the process of inhaling oxygen-rich air and exhaling carbon dioxide-rich air.
What is groundwater 6th class
Chemistry. Standard VI. Groundwater is the water that can be found underground in the crevices and cracks of soil, sand, and rock. It is stored in and moves slowly through geologic formations of soil, sand, and rocks called aquifers.
How are clouds formed Class 6
Ans: Since the suns heat causes the water on earth to evaporate, clouds are created when water vapour present in the air at high altitude condenses to form minute droplets of water that are visible.25 September 2019
What are the uses of air class 6
Important Uses of Air
- maintain growth and life.
- Combustion.
- Upholding the temperature.
- Provider of energy
- Photosynthesis.
What is water cycle for Class 6
The water cycle is the continual transfer of water from the Earth to the atmosphere and back again through the processes of evaporation, condensation, and precipitation.
What is water in the air
The amount of water vapor in the air is referred to as humidity, and it is really just water in the form of a gas that is invisible, colorless, odorless, and tasteless.
What is water vapour for Class 5
Water vapor, also known as water vapour or aqueous vapor, is the gaseous phase of water and one of the states of water found in the hydrosphere. Like most atmospheric constituents, water vapor is transparent. It can be created by boiling or evaporating liquid water, as well as by the sublimation of ice.
What is the use of nitrogen for Class 6
Nitric acid salts include significant compounds like potassium nitrate, ammonium nitrate, and nitric acid. Liquid nitrogen is used as a refrigerant for transporting food and freezing purposes. Nitric acid is produced when ammonia is produced and then used as a fertilizer.
What is the composition of air for Class 6
Nitrogen, which makes up the majority of air, has a%age of 78.09%, followed by oxygen, which makes up 20.95%, argon, which makes up 0.93%, carbon dioxide, which makes up 0.04%, and other inert gases in small amounts.
What do you know about air
The Earths atmosphere is primarily made up of nitrogen, which makes up about 78% of the air, and oxygen, which makes up about 21%. Air also contains small amounts of many other gases, including carbon dioxide, neon, and hydrogen.
What is the importance of carbon dioxide Class 6
Answer: (a) Green plants produce their own food through photosynthesis by absorbing carbon dioxide from the air and producing food in the presence of chlorophyll and sunlight.
How will you prove that air supports burning Class 6
Take a small burning candle and place it inside a glass jar to block the air supply. After a few minutes, the candle will burn out because the air supply has been cut off.
Is air a composition
Dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and trace amounts of other gases. Air is a mixture of nitrogen, oxygen, carbon dioxide, water vapors, and other gases. It also contains dust particles.
