Answer 1

Answer:

Hydrogen has the following physical parameters:

melting temperature — (-259.2) degrees Celsius;

boiling temperature — (-252.76) degrees Celsius;

in this interval, hydrogen is a colorless liquid without any smell;

at high pressure, snow-like crystals of solid hydrogen form

At standard temperature and pressure, hydrogen is a nontoxic, nonmetallic, odorless, tasteless, colorless, and highly combustible diatomic gas with the molecular formula H2. Hydrogen is also prevalent on Earth in the form of chemical compounds such as hydrocarbons and water.
