Which contains more oxygen inhaled air or exhaled air?
Inhaled air contains more oxygen than exhaled air. When you breathe in, oxygen is taken into your lungs and absorbed into your bloodstream. When you breathe out, you release carbon dioxide produced by your body and some of the oxygen has been used up.
Why is there oxygen in the air?
Oxygen is present in the air due to photosynthesis, where plants and algae use sunlight to convert carbon dioxide into oxygen. This process has been occurring for billions of years, continually replenishing the Earth's atmosphere with oxygen.
What is always present in the atomosphere?
Oxygen is a gas that is always present in Earth's atmosphere. It makes up about 21% of the air we breathe and is essential for sustaining life.
Is there more oxygen on the floor?
Generally, oxygen levels remain constant in a room regardless of height. However, due to air circulation, oxygen may be slightly better at floor level in areas with good ventilation. It is always advised to prioritize regular ventilation and fresh air circulation in enclosed spaces for optimal oxygen levels.
What was the original name for oxygen?
The original name for oxygen was "dephlogisticated air." It was called this because it was believed to be air that had been purified by the removal of phlogiston, an outdated concept in chemistry.
How much oxygen does exhaled air contains approximately?
A small percent . exhaled air always contains oxygen .
When there was no oxygen did the water have oxygen in it?
It had to. So yes in a way there always was oxygen. Because if there was no oxygen to would be just hydrogen in the air.
What is always in the air?
Oxygen, nitrogen, and various other gases are always present in the air. These gases are essential for supporting life on Earth.
The lungfish always lives in oxygen-poor water and can do so because?
It can supplement its oxygen by using oxygen from air as well as water.
Why you inhale oxygen only?
when you inhale air into your lungs the concentration of oxygen in the blood can be no greater than that in the air.As the blood reaching the lungs is lower in oxygen there is transfer from the air to the blood stream until the concentrations stabilise.However there is no active transfer.Therefore there will always be Oxygen in exhaled air even if the initial oxygen concentration in the blood is zero as the air oxygen and the blood oxygen will reach a steady state equilibrium
Which contains more oxygen inhaled air or exhaled air?
Inhaled air contains more oxygen than exhaled air. When you breathe in, oxygen is taken into your lungs and absorbed into your bloodstream. When you breathe out, you release carbon dioxide produced by your body and some of the oxygen has been used up.
The air you breathe is made of 21 percent oxygen and 78 percent nitrogen The oxygen in air is the?
It's the oxygen. Since oxygen doesn't dissolve into nitrogen - air is a mixture, not a solution - you can't call it the solute and the nitrogen the solvent, which may have been the answer you thought you were going to get.

What is the average oxygen level in the air at 5000 ft?
The average oxygen level at 5000 ft is around 18% less than at sea level. This means the oxygen concentration at 5000 ft is approximately 15-16%.
