Can Humans Breathe Liquid Oxygen? 1

After you let it become a gas and warm up, yes.Liquid oxygen is somewhere between −361.82 °F and −297.33 °F

How long can a vehicle stay fueled before the liquid oxygen gets too warm?

Normal vehicles that use LOX, use it at the normal temp (-183C) and what they do is let the LOX boil off, and refill it right up to the latest possible moment their hardware allows.The Falcon 9 1.1 Full Thrust (or whatever it is finally called) uses the LOX supercooled to -207C which is a different problem. The answer is unclear and is obviously something SpaceX is working on figuring out since it seems based on an Elon Musk tweet that the ignition issue was due to rising LOX temperatures.

Is the Helios Liquid Oxygen system as good as it sounds?

I use it, In therory a refill last 8 hours, getting a unit that works right is a different story Another thing she must be able to trigger the sensor. It's a pulsed system and other folks can hear it

We need to light something on fire quickly/safely. details below.?

Pour several dewers of liquid oxygen over it before you light it. You might want to use a long long pole to light it though

Say you fell into a lake of liquid oxygen, could you breathe it in and not drown?

Educated Hypothesis:No, because the pressure of your body heat would subliminate the liquid due to rapid and vapid expansion, you would bounce/hover over the lake as you stabilized the surface tempurature and slowly came to a frigid and frozen stop, Then you would further freeze and sink to the bottom of the lake. That is if you/ the lake stayed intact during the volatile reaction at the beginning

is space exploration reliant upon fossil fuel in any way....?

directly, lubricants. indirectly, fuels. most boosters use liquid hydrogen and liquid oxygen. these require energy to prepare.

What happens when you microwave liquid oxygen?

pure oxygen is flamable.as it expands as long as it's not mixing with hydrogen therefore neutralizing it's flamability the potential energy of the gas will increase as the molecules of the oxygen expand. the microwace could blow up in 2 ways.if the seal on the door is airtight the door or the weakest point of the microwave would break, releasing the trapped expanding gas.it would sort of pop the microwave like a balloon would pop if it were overfilled. or a spark generated by the microwave could ignite the expanding molecules of oxygen and hence fowarth cause an explosion. but if the seal is not airtight on the microwave, than there might not even be an explosion at all because the gas is venting out into the atmosphere as it expands.if the microwave does not arc a spark then no gas ignition. .meaning no explosion.

What does solid oxygen look like?

Liquid oxygen is often photographed, but solid oxygen, not so much. I would guess that solid oxygen would be a pale blue, amorphous material.Liquid oxygen:Solid oxygen forms at normal atmospheric pressure at a temperature below 54.36 K (−218.79 °C, −361.82 °F). Solid oxygen O2, like liquid oxygen, is a clear substance with a light sky-blue color caused by absorption in the red part of the visible light spectrum. Solid oxygen - Wikipedia

Oxygen - Wikipedia

The NFPA 704 standard rates compressed oxygen gas as nonhazardous to health, nonflammable and nonreactive, but an oxidizer. Refrigerated liquid oxygen (LOX) is given a health hazard rating of 3 (for increased risk of hyperoxia from condensed vapors, and for hazards common to cryogenic liquids such as frostbite), and all other ratings are the same as the compressed gas form.
