Question

The volume of a gas is increased from 0.5 L to 4.0 L while the temperature is held constant. The pressure of the gas will go from 24 atm to ?

Answer 1

From Boyle's law the volume of a fixed mass of a gas is inversely proportional to the pressure at a constant absolute temperature. Thus; K = PV                          Hence; P1V1 =P2V2                                                                                                      0.5 × 24 = 4× P2                                                                                                      P2 = 12/4 = 3 atm                                                                                      Therefore; the pressure will go from 24 atm to 3 atm
