Calculate the mass 15.0L of NH3 at 27 degree celcius and 900 mm Hg.​

answermeridional ;

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but

i think tornado but not 100%
