Bernoulli’s Principle explains that faster airflow over the wings creates lower pressure, producing lift that keeps the airplane in the air.

Explanation

N₂ makes up about 78% of Earth’s atmosphere.

It is inert, non-toxic, and non-polluting.

NO, CO, and N₂O are harmful gases that contribute to air pollution and environmental problems.

Explanation

Osmosis is the movement of water molecules through a semipermeable membrane from an area of higher water concentration to lower concentration.

It is a vital process in biological systems for maintaining cell balance.

Explanation

• Carbon dioxide (CO2) is the gas from the atmosphere that plants absorb through their leaves.
• It use as a reactant in photosynthesis, combining it with water and light energy to produce glucose and oxygen.

Explanation

Primary pollutants are emitted directly into the air from sources like vehicles and industries.

Examples include carbon monoxide (CO), sulfur dioxide (SO₂), and nitrogen dioxide (NO₂).

Explanation

Hydrogen is present in the atmosphere in trace amounts, making it the least common among the listed gases.

Nitrogen (~78%), Oxygen (~21%), and Argon (~0.93%) are much more abundant.

Explanation

Radon (Rn) is a radioactive gas formed from the decay of uranium and radium found in rocks and soil.

He (Helium): Helium is present in trace amounts in the atmosphere.

Ne (Neon): Neon is also present in trace amounts in the atmosphere.

Ar (Argon): Argon is the most abundant noble gas in Earth's atmosphere, making up about 0.93% of the air. 

Explanation
