20 grams of a gas occupies 100 cc volume at pressure 105 dyne/cm2 . If during isothermal process the pressure is changed to104  dyne/cm2, the volume of the gas in cc will be:

gas equation in isothermal process is PV=constant         P1V1=P2V2hereinitial pressure of gas, P1=105 dynecm-2,Final pressure of gas,P2 =104 dynecm-2   V1=100cc,V2 initial,final volume of gas     substitute the values in above gas equation   ⇒105×100=104×V2 ⇒  V2=1000 cc   is final volume of gas
