Question

Note down the properties of hydrogen gas.

Answer 1

Hi friend,
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;
in spe­cial con­di­tions, hy­dro­gen is ca­pa­ble of mov­ing to a met­al state;
hy­dro­gen is in­sol­u­ble in wa­ter, so it can be ob­tained in the lab­o­ra­to­ry by the wa­ter dis­place­ment method;
in or­di­nary con­di­tions, hy­dro­gen is a col­or­less gas with­out any smell or taste. It is a com­bustible and ex­plo­sive sub­stance;
it dis­solves well in met­als be­cause of its abil­i­ty to dif­fuse through their thick­ness;
hy­dro­gen is 14.5 times lighter than air;
the crys­tal struc­ture of the sim­ple sub­stance is molec­u­lar, and the bonds are weak, which means it breaks down eas­i­ly.
