What is the coldest liquid?
Liquid hydrogenCurrently voted the best answer.
Liquid hydrogen is the coldest substance known to man, minus 400 degrees.
ALSO: A Bose–Einstein condensate (BEC) is a state of matter of bosons confined in an external potential and cooled to temperatures very near to absolute zero (0 K, ?.
Can oxygen exist as a liquid and solid?
Along certain pressure-temperature combinations it can be a gas and a liquid or a liquid and a solid at the same time. And at a point called the triple point, it can exist in all 3 states simultaneously.
How dangerous is liquid oxygen?
The hazards associated with liquid oxygen are exposure to cold temperatures that can cause severe burns; over-pressurization due to expansion of small amounts of liquid into large volumes of gas in inadequately vented equipment; oxygen enrichment of the surrounding atmosphere; and the possibility of a combustion …
Can liquid oxygen kill you?
Don’t do it, it is not just hooey it is dangerous. Liquid O2 is a cryogenic liquid, it is used to rapidly freeze things like human tissue. … As mentioned, true liquid oxygen would likely kill you pretty quickly if you tried to drink it.
Is Solid air possible?
Yes. Air can be solidified by compression and cooling.
Is solid hydrogen possible?
The squished hydrogen is a precursor to a state of matter first proposed in the 1930s, called atomic solid metallic hydrogen. When cooled to low enough temperatures, hydrogen (which on Earth is usually found as a gas) can become a solid; at high enough pressures, when the element solidifies, it turns into a metal.
What temperature is liquid oxygen?
Liquid oxygen is a cryogenic liquid. Cryogenic liquids are liquefied gases that have a normal boiling point below –130°F (–90°C). Liquid oxygen has a boiling point of –297°F (–183°C).
Is solid helium possible?
Helium is one of only two natural elements that has never been observed bonding to another element in a compound. … At normal atmospheric pressure helium does not solidify. At 25 atmospheres of pressure helium is a solid at 0.95 K. As the pressure rises, the temperature at which solid helium exists also rises.
Can liquid oxygen explode?
Liquid oxygen on its own does not burn or explode it is an oxidizer. If you mix it with organic materials such as paper, oils etc it acts as an oxidiser and those materials burn very vigorously, most will need a source of heat to initiate the reaction. here is an example of liquid hydrogen burning in liquid oxygen.
Can you eat solid oxygen?
oxygen is an extremely powerful oxidizer. Eating its solid form at temperature of −218 °C will obviously freeze you to death. … And swallowing an excessive amount of oxygen into your throat makes the flammable fat in your throat react with the oxygen immediately. And burn up.
How hard is solid oxygen?
Solid oxygen was found to behave as a plastic material with a shear strength of approximately 0.3 MPa 10 K below its melting point. Solid oxygen becomes increasingly stronger and brittle as its temperature is decreased, giving a shear strength of over 3.5 MPa at low temperatures.
Is oxygen a solid liquid or gas?
Oxygen is a gas at room temperature. If the normal melting point of a substance is below room temperature, the substance is a liquid at room temperature.
