What State Will Helium Be At Room Temperature

452 07 f and above the lambda point of 2 1768 k 270 9732 c.

What state will helium be at room temperature. The temperature at which the liquid gas phase change occurs. Most of the elements on the right side of the table are gases at room temp. Helium is the only element that does not solidify under ordinary pressures and remains a liquid even at absolute zero. Liquid helium is a physical state of helium at very low temperatures if it is at standard atmospheric pressures.

It boils at approximately 452 degrees below 0. 0 0 1. Helium the second most abundant element in the universe was discovered on the sun before it was found on the earth pierre jules césar janssen a french astronomer noticed a yellow line in the sun s spectrum while studying a total solar eclipse in 1868. At room temperature this requires about 114 000 atm.

Its boiling point and critical point depend on which isotope of helium is present. At room temperature helium is an odorless tasteless colorless gas. Liquid helium has a boiling point of about 3 2 kelvin or 266 8 celsius. The state of matter at room temperature for the element europium is a liquid.

Below 2 18 k thermal conductivity of helium 4 becomes more than 1 000 times greater than that of copper this liquid form is called helium ii to distinguish it from normal liquid helium. 455 7518 f the isotope helium 4 exists in a normal colorless liquid state called helium i. Density g cm 3 density is the mass of a substance that would fill 1 cm 3 at room temperature. It has very low boiling and melting points meaning that it is generally found in the gas phase except under the most extreme of conditions.

Sir norman lockyer an english astronomer realized that this line with a wavelength of 587 49 nanometers could not be produced by any. Sublimation the transition of a substance directly from the solid to the gas phase without passing through a liquid phase. At standard pressure the chemical element helium exists in a liquid form only at the extremely low temperature of 269 c about 4 k or 452 2 f. Below its boiling point of 4 22 k 268 93 c.

Liquid helium may show superfluidity. Relative atomic mass the mass of an atom relative to that of. Helium is a gas at room temperature. No helium is not a liquid at room temperature.

Helium 4 is unique in having two liquid forms. Cold fusion is a hypothesized type of nuclear reaction that would occur at or near room temperature it would contrast starkly with the hot fusion that is known to take place naturally within stars and artificially in hydrogen bombs and prototype fusion reactors under immense pressure and at temperatures of millions of degrees and be distinguished from muon catalyzed fusion.
