Excuse me can anyone explain why if a gas has a higher boiling points than other two gases condenses more easily than other those two gases if they have lower boiling points?????? like ammonia and(nitrogen and hydrogen forming it)

Let us take example of known substances => water and ethanol,their boiling points are 100 and 78 respectively, now both will be gases at a temp. higher than their boiling points say at temp. 110,both are gases.[Temp. below their boiling points(& higher than m.p) they will be liquids].Now if we start to decrease the temp. [cool it] ,it will first reach a temp. of 100 right so first steam(water vapour) will condense,then it will cool to 78 so at this point ethanol vapour will condense.So now hope u understan why the gas with higher boiling point condenses first!!
