Owhat volume must 175 l of air at 1.0 atm be compressed to yield a pressure of 5.2 atm? (you can assume constant temperature.)

As we know, 
                 P1V1=P2V2
                P1=1atm
                P2=5.2
                 V1=175
                    V2= required
   so put the values and grab your answer
   which should be nearly 33.6 L

Iwould you figure it out but you don't have a picture or in your question as to what the physical property you're looking for is
