Cаlculаte the vоlume оf аir, in cm3 оr mL, in a diver's lungs when he/she is at the surface of a lake if the volume of air when the diver is at a depth d=2m below the surface of a lake is V@ depth d= [v] cm3 ?   Assume the diver does not let go of any air in his lungs.   pat depth 2 m=19,600Nm2+101,000Nm2   pat surface=1atm=101,000Nm2   psurface⋅Vsurface=nRTsurface   pat depth d⋅Vat depth d=nRTat depth d   Tat depth d=Tsurface
