People use air for various purposes beyond breathing, such as in the operation of engines and machinery, where air is essential for combustion. It is also used in the production of sound, as in Musical Instruments and public speaking, where air vibrations create audible waves. Additionally, air pressure is crucial in activities like cooking with convection ovens and in various scientific processes, including weather forecasting and aerodynamics.
by breathing
People use air for breathing, supporting combustion for cooking and heating, and as a medium for transportation, such as in inflatable devices or hot air balloons.
People, and many other air breathing creatures
Scuba Breathing Apparatus.
by breathing and storing air inside and releasing it
Approximately 21% of the air is oxygen, which we use for breathing. The remaining 78% is nitrogen, which is mainly inert and not used for respiration.
To clean oil from a compressed breathing air cylinder, you can flush the cylinder with clean air to remove any residual oil. You can also use a specialized cleaning solution designed for air cylinders to remove oil contamination. It is important to follow proper safety procedures and regulations to ensure the cylinder is safe for use with breathing air.
In space, people call it a vacuum because there is no way you can breath because the are no oxygen molecules in space for you to breath. That is where the backpack comes in. The bag is a place where it holds all the air for you to breath, there is a limited amount of time for you to breath because you are inhaling good air and releasing bad air. If you keep breathing the bad air, you can die from breathing you bad air (carbon dioxide) too much. Th backpack holds the air for you, it is just like an air tank you use for swimming. Have you ever seen in shows how some people use the paper bag to breathe when they are nervous and sometimes they faint? That happens because of one of two reasons. They were breathing too fast (it can happen) or because they are breathing there air too much.
It takes in and releases air through a blowhole atop its head.
air is in the water because although sea animals use this while breathing under the water
Air is essential for breathing, providing oxygen for cellular respiration. It also helps regulate the Earth's climate by influencing weather patterns. Additionally, air plays a role in sound transmission and can be used in various industrial processes.
On average, humans use about 5-10% of their daily energy expenditure on breathing. The energy is mainly used for the muscles involved in the breathing process and to warm, filter, and humidify the air we breathe.
