Question

Draw a flaw diagram shows the
process of obtaining gases from air?
ans = air is a homagenous mixture. it we want oxygen gas from air we have to separate out all the other gases present in the air .
The air is compressed by increasing the pressure and is then cooled by decreasing the temperature to get liquid air . This liquid air is allowed to warm- up slowly in a fractional distillation column, where gases get separated at different heights depending upon their boiling points .

(air)
|
compress and cool by increasing pressure and decreasing temperature.

(liquid air )
|
allow to warm up slowly in fractional distillation column gases get separated highest .


(1) = Boiling points ( c⁰) =

( oxygen = -183 )
( argon = - 186 )
( nitrogen = - 196 )

(2) = c⁰ air by volume = ( oxygen = 20.9 )
( argon = 0.9 )
( nitrogen = 78.1) .

PLEASE YE TABLE BANA KAR LIKHNA HI .
