Dry air (γ=32) at atmospheric pressure is suddenly compressed to 14th of its original volume, the pressure will be
10 atm
8 atm
3 atm
6 atm
Pressure P1=P=1 atm to find P2 given volume V1=V and :V2=V4 adiabatic process(it is a sudden process) relation between P and V isPVγ=Constant P1P2=V2V1γ substitute the given values in above equation PP2=V4V32 ⇒PP2=18P2=8P given P= 1 atm ⇒P2=8 atm
