The curve between the critical point and the triple point shows the hydrogen boiling point with changes in pressure.
Hydrogen phase at room temperature.
The hydrogen phase diagram shows the phase behavior with changes in temperature and pressure.
Metallic hydrogen is a phase of hydrogen in which it behaves like an electrical conductor this phase was predicted in 1935 on theoretical grounds by eugene wigner and hillard bell huntington.
At room temperature helium is an odorless tasteless colorless gas.
The pressure required to reach this point is called the critical pressure which for hydrogen is pu 1 239 mpa pu 179 7 psi.
Hydrogen is the raw fuel that most stars burn to produce energy.
Hydrogen also known as h2 or e 949 belongs to the class of inorganic compounds known as other non metal hydrides these are inorganic compounds in which the heaviest atom bonded to a hydrogen atom is belongs to the class of other non metals.
Incidentally there are two established storage technologies for pure hydrogen in vehicles.
It is estimated that 90 of the visible universe is composed of hydrogen.
When the dual phase alloy is charged with hydrogen at room temperature hydrogen diffuses primarily through β phase and α β phase boundary and then forms β h solid solution accompanying a few percent of volumetric expansion fig.
Hydrogen is a gas at standard conditions.
Helium is the only element that does not solidify under ordinary pressures and remains a liquid even at absolute zero.
Hydrochloric acid the aqueous solution of hydrogen chloride is also commonly given.
Hydrogen can be found anywhere throughout the human cell such as in lysosome endoplasmic reticulum golgi and peroxisome.
In order to accommodate the volumetric expansion of β phase the adjacent α phase has increased number.
However at very low temperature and or high pressures the gas becomes a liquid or a solid.
At high pressure and temperatures metallic hydrogen can exist as a liquid rather than a solid and researchers think it might be present in large quantities in the hot and gravitationally compressed.
At room temperature and under standard pressure conditions hydrogen is a gas that is tasteless odorless and colorless.

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.
Composed of a single proton and a single electron hydrogen is the simplest and most abundant element in the universe.
The compound hydrogen chloride has the chemical formula h cl and as such is a hydrogen halide at room temperature it is a colourless gas which forms white fumes of hydrochloric acid upon contact with atmospheric water vapor hydrogen chloride gas and hydrochloric acid are important in technology and industry.
