Because it would otherwise mix with air, making it impure.

Why is oxygen gas usually stored under pressure in metal cylinder?
It can exploded.
What is the temperature range for liquid oxygen?
Under normal atmospheric pressure oxygen is a liquid at temperatures ranging from -218.79 degrees Celsius to -182.96 degrees Celsius. This works out to -361.82 degrees Fahrenheit to -297.33 degrees Fahrenheit.
How hydrogen can be made into a liquid?
To turn hydrogen to a liquid, you have to either lower the temperature or increase the pressure or both. At one atmosphere (the air pressure at sea level) hydrogen liquefies at 20 degrees Kelvin (about -423°F). Any gas can be turned into liquid by cooling it down under high pressure. with a pressure engine
How is potassium stored?
The pure metal must be stored under oil to protect it from oxygen and water vapor in the air.
What color weight density melting point luster hardness is oxygen?
Oxygen is a gas under normal conditions and so has no hardness or luster. The melting or freezing point of oxygen at standard temperature and pressure is 54.36 K ​(−218.79 °C, ​−361.82 °F) The density of oxygen gas at standard temperature and pressure is 1.429 g/L. the density of liquid oxygen at its boiling point (−182.962 °C or ​−297.332 °F) is 1.141 g/cm3. The atomic weight is about 15.999 Oxygen as a gas has no color. As a liquid it is a light blue.
Why is pure oxygen stored as liquid under pressure?
Oxygen stored as liquid is highly flammable.
Why is oxygen gas usually stored under pressure in metal cylinder?
It can exploded.
Which fuel is stored in tanks it is not under pressure it flows along a pipe to where it is needed?
liquid
Would a solution under high pressure have more gas in it than a solution under low pressure?
A sol'n under HIGH pressure has more gas in it. The high pressure is working against the much smaller vapor pressure of the liquid. If they equal then the liquid is at it's boiling point. Additionally applying pressure to a solution keeps dissolved gasses inside the solution such as Oxygen or Carbon Dioxide (Think of a Cola can. It is stored under pressure and the fizz stays in the liquid. Then you open the can and release the high pressure and the carbon dioxide starts to bubble out of the solution. It was not doing this before you opened the can and lowered the overall pressure)
What kind of fuel does a shuttle use?
The main three engines use liquid hydrogen and an oxygen oxidizer. These are delivered under pressure to fuel the main engines.A space shuttle uses a combination of liquid oxygen and liquid nitrogen. Solid rocket boosters use a rubberized compound of aluminum and perchlorate oxidizer.Orbiter main engines use liquid hydrogen / liquid oxygen that is stored in the external tank.Hydrogen fuel is burned with oxygen-rocket engine.
Is liquid petroleum gas a gas or a liquid?
Under normal temperature and atmospheric pressure conditions propane is gaseous. However, when the temperature is reduced to below −42.09 °C or when it is stored under high pressure (approx 177 psi), it takes the form of a liquid.
Can anhydrous ammonia become liquid ammonia?
Anhydrous ammonia is usually stored as a liquid by keeping it under pressure. It is more efficient to store it that way than as a gas.
Can oxygen exist as a liquid?
Yes, but under atmospheric pressure it must be cooled to 90 Kelvin, about -183 Celsius.
Does a liquid have a form?
All substances have a liquid form, but may not be present in nature. Under extreme pressure and temperature circumstances, liquid oxygen can be created, in fact, it is used to fuel space rockets.
What is the temperature range for liquid oxygen?
Under normal atmospheric pressure oxygen is a liquid at temperatures ranging from -218.79 degrees Celsius to -182.96 degrees Celsius. This works out to -361.82 degrees Fahrenheit to -297.33 degrees Fahrenheit.
Is nitrogen dioxide a solid liquid gas?
Depends on the conditions that is held under; Pressure, Temperature. At ATM conditions it exists as a gas, but when stored as a pure substances, it is usually pressurized and cooled as a liquid.
Is LPG a gas or liquid?
LPG stands for Liquefied Petroleum Gas, which means that it is a gas which has been compressed to liquid in cylinders. For more info, go this website: http://en.wikipedia.org/wiki/Liquefied_petroleum_gas
