How long a 100 lbs oxygen tank will last on the surface of moon?
forever probably, unless a meteor hits it.
If the Nitrogen and Oxygen were not replaced in the atmosphere how long would our present supply of these gases last?
If nitrogen and oxygen in the atmosphere were not replenished, they would last a very long time due to their stability and abundance. Nitrogen makes up about 78% of the atmosphere, while oxygen constitutes about 21%. The primary sources of oxygen, such as photosynthesis from plants, are crucial for its continuous supply; without these processes, oxygen levels would gradually decrease over centuries. However, nitrogen is inert and doesn't get consumed in significant amounts, meaning it could theoretically last indefinitely without replacements.
How long has oxygen been fully present in the atmosphere?
500 million years
How long do nebulae last?
light years
How long does rainbows last?
Rainbows usually last for a very few hours about 2 to 6 hours.
How long would a fire last with a limited amount of oxygen?
The is not enough information to answer this. We need to know what is burning, how much, and how fast, and how much oxygen we have.
How long did the Nazi book burning last?
not very long
How long can flame last without air?
Combustion or burning requires oxygen of the air. So, if there's no air, the flame will extinguish immediately because there's no oxygen.
How can the burning of forests change oxygen levels?
Burning forests release carbon dioxide, which reduces the amount of oxygen produced during photosynthesis. This can lead to a decrease in oxygen levels in the immediate area, particularly if the burning is extensive and long-lasting. However, the overall impact on global oxygen levels is minimal due to the Earth's large oxygen reserves.
How long can oxygen last?
it can last for as long as you can hold your breath. after that time you have 3 minutes before you pass out.
How long does a car last once it starts burning oil?

How long do oxygen absorbers last before they need to be replaced?
Oxygen absorbers typically last about 1-2 years before they need to be replaced.
Why can a person last 1 minute without oxygen?
A person can last 4 minutes without oxygen, longer in extreme cold. It takes that long for the body to use up the oxygen in the blood.
How long will a c oxygen cylinder last on 2lpm?
A C oxygen cylinder typically holds about 3400 liters of oxygen. At a flow rate of 2 liters per minute, it will last for approximately 28 hours.
How long will a ml6 oxygen cylinder last?
An ML6 oxygen cylinder, when "charged" to normal pressures, holds 170 liters of oxygen. How long that will last depends on a number of factors. If the flow is set to 2 liters per minute continuous then it will last less than 1 and 1/2 hours. If an oxygen conserving device is used (they give the gas in pluses when breaths are taken) it can last over 4 hours.
Why is dangerous to burn coal in a closed room?
Burning coal produces carbon monoxide, a colorless and odorless gas that can be deadly if inhaled in a closed room. This gas can displace oxygen in the air, leading to suffocation. It is important to ensure proper ventilation when burning coal to prevent carbon monoxide poisoning.
