Isothermal process involving changes in Volume and Pressure

May 2019
Equipped diver is at the depth of 21 m, where the pressure is 2,1 bar(3,1 abs). The diver breathes air that is pressurized to 2 bar. What would the final lung capacity be if the diver held their breath while ascending to the surface? diver lung capacity is 5.1 L and temperature is constant


P1= 2,1bar (3,1 bar absolute), V1=5.1L P2= 1 bar

V2 = 15,3L?
is that right'?
