Around 21% of Earth's atmosphere is oxygen, but only a small percentage is needed to support human life. Concentrations above 35% oxygen can be toxic and increase the risk of fires.
Around 16% of oxygen in the air is needed to support fire. This level is known as the minimum oxygen concentration required for combustion.
The minimum percentage of oxygen required for human life to survive is around 16-17%. If the oxygen level drops below this, it can lead to hypoxia, which can be life-threatening if not addressed promptly.
The mass percent of oxygen is approximately 21% in Earth's atmosphere.
The percent of oxygen in dry air is approximately 21%.
A minimum of 16% oxygen concentration is needed to sustain a fire. This level is known as the lower flammability limit (LFL) for oxygen. Below this threshold, there is not enough oxygen to support combustion and ignite a fire.
The percent of oxygen is 27. this increases the natural percent of 21 by 6 percent causing living organisms to have too much oxygen.
Around 16% of oxygen in the air is needed to support fire. This level is known as the minimum oxygen concentration required for combustion.
No, there is no oxygen for them.
The atomic symbol for oxygen is O. The chemistry symbol for water is H2O. Water covers about 70 percent of our planet & is needed to support life. Without it, we would not exist.
yes the milky way can support life, but it can't support life too long.
Hypoxia is the term used to describe water with too little oxygen to support life.
no the moon cannot support life because it has little oxygen so nothing could live there
water and oxygen
Life, Oceans and a high percent of oxygen in the atmosphere

Saturn can't support life because it has no oxygen and has poisonous gases in which no life can survive. ---- Plus the pressure is a lot greater than ours
