Air for Breathing and Combustion
How does Air Support Life on Earth?
Air supports life by providing oxygen essential for respiration in humans, animals, and plants. It also regulates temperatures, facilitates weather patterns, and enables sound transmission.
What are the Main Components of Air, and What roles do they play?
The main components of air are nitrogen (about 78%) and oxygen (about 21%), with trace amounts of other gases like argon, carbon dioxide, and water vapor. Nitrogen provides inert stability, while oxygen is vital for respiration and combustion.
What is air’s scientific name?
In scientific terms, “air” is a mixture of substances, hence it lacks a name. “Pure” substances like oxygen (O2) and water (H20) can have chemical names.
Why is Air Essential for Breathing?
Air contains oxygen, which is vital for the process of respiration in humans and animals. When we breathe in air, the oxygen is absorbed into the bloodstream and transported to cells throughout the body, where it is used for cellular respiration to produce energy.
How does Combustion Contribute to Air Pollution?
Combustion processes can release pollutants and greenhouse gases into the air, contributing to air pollution and climate change. Examples of pollutants include carbon monoxide, nitrogen oxides, and particulate matter.
What Happens if we don’t have Enough Oxygen in the Air we Breathe?
Without enough oxygen, our cells cannot perform cellular respiration effectively, leading to health problems and potentially even death.
Air for Breathing and Combustion
Air is one of the elements that sustains life on Earth. Air serves two crucial functions – sustaining life through respiration and fueling combustion processes. The air around us makes up the Earth’s atmosphere, which extends about 11 kilometres high. As we get closer to the ground, the air becomes thicker because of gravity.
This air has the right mix of gases and pressure to support life. High in the atmosphere, the ozone layer acts like a shield which protects us from harmful rays from space. In this article, we will read about how air is used in respiration and combustion.
