oxygen tank?
cylinder of compressed Oxygen
is carried on a spacecraft
headed for Mars. The
compressed gas cylinder has a
volume of 14000 L and is
filled to a pressure of 151
atm at 236 K. The maximum
pressure the cylinder can hold
is 1000 atm.
The molar mass of Oxygen is 32
g/mol.
Boltzmann's constant = 1.38

I assume that it's desired to assume that all gases involved are ideal. There is no need to calculate the number of moles of oxygen. All that is necessary is to use the fact that P ~ T/V —that is, the pressure of a fixed amount of gas is proportional to the temperature and inversely proportional to the volume. Using this, we see that as the gas originally in the cylinder has a pressure of 151 atm at a temperature of 236 K and in a tank of 14,000 L, when it has a temperature of 300 K and is in a tank of 10,000 L, it will have a pressure of P = 151*(300/236)*1.4 = 268.7 atm. This will be the partial pressure in the holding tank of the added oxygen. To find the new pressure in the holding tank, we must add the pressure of the gas initially present, giving an answer of P + 22 atm = 290.7 atm. |

Why does an oxygen tank I was watching a television
show, and a match was lit
around an oxygen tank, and the
oxygen tank exploded. Why do
oxygen tanks explode when a
match it lit around it? And
why don't matches explode when
they're lit in the air, when
air is oxygen?

The tank itself exploded because it was a TV show and the pyrotechnics people set off the charge they had carefully rigged to it. Most folks believe the fiction because they don't understand either chemistry or physics and the forces that would actually be required. It's not because the gas confined within the tank had some sort of magical ability to burst the thick metal walls of the tank just because the small flame of a lit match was nearby. Even in an industrial fire, a tank will only explode if it becomes so hot that the pressure inside the tank increases to the point that will rupture the tank. The safety vent built into the valve will usually release the contents in a more controlled manner long before that happens. In chemical terms an explosion is just a rapid form of combustion - a chemical reaction between two compounds that releases energy. One type of combustion involves oxygen. Oxidation (such as rusting), burning, and chemical explosions are all the same thing - only the time frame is different. Things that might burn in an atmosphere that is ~ 20% oxygen will burn much quicker as the level approaches 100%. Don |

What is the closest a My mother is in dire need of
an oxygen tank. But the Dr.
won't give her one as long as
she's smoking. She will not
quit. She said that's the only
thing in life that she enjoys.
She has lack of oxygen to the
brain & she needs the oxygen,
bad. She's started acting
strange & I know that's why. I
dont want her to die because
she doesn't have an oxygen
tank, but like I said, she
wont quit smoking. My sister
says we should tell the Dr
she's quit, so she can get the
oxygen she so desparately
needs. I dont like to lie.
Plus, the chance of explosion
(due to a cigarette being near
oxygen) worries me. Mom smokes
outside. My sister thinks if
the oxygen tank is in the
house & mom goes outside to
smoke, that there shouldn't be
a problem. I want an opinion
of someone who would better
know. Would it be safe to do
that? Is there a certain
distance that smoke should be
kept away from an oxygen tank?
Only serious answers please.
Thank you.

I have worked around oxygen, acetylene,butane,propane and gasoline and I can tell you that the heat from a cigarette cannot light any of these gases. It is the match or lighter that can cause the gases to ignite or explode. Their is some technical jargon about ambient temps. and at what heat range these gases ignite at but what the doctor is concerned about is the lighting of the cigarette that can cause the oxygen going to her nose that can explode. My father was in the same situation and the patches along with the gum curbed his nicotine craving. As far as the hand to mouth urge he handled that with spaghetti . He took a piece of spaghetti and put it in and took it out and as it softened he just chewed it up. But by taking it and holding it in his mouth and taking it out that seemed to satisfy that reflex action. On the darker side though of smoking and oxygen I have heard of a couple people expeirencing a small explosion and severe burns from lighting a cigarette with the nose tubes in . My daughter works in the Emergency room of a local hospital and she is my source of this . My expeirence comes from being an autoworker and an avid backyard mech with friends who are the same and we can't light any torches with a cigarette only with a lighter or a striker that creates a spark |
