A 93L sample of dry air is cooled from 145 to-22 under constant pressure.What is the final volume?

  • chemistry -

    From 145 what to -22 what? I assume that is temperature of some kind; therefore,
    (V1/T1) = (V2/T2)
    If 145 and -22 are in kelvin that can be used directly; if in some other units you must change to kelvin to work the problem.
