superheated soild
supercooled solid
superheated liquid
supercooled gas
supercooled liquid

in soil bacteria cause decay of life into ammonia, process is
N fixation
N Cycle
ammonification
fertilization

we cant use air N , because
our need is already fulfilled
our cells nont need N
it is too much in air
our cells RBC has full capacity to carry any gas( O N C etc) to body cells
we cant fix it
