A scuba diver has his lungs filled to 3 liters when 10 meters below the surface and at a temperature of 10 oC. The diver holds his breath while quietly rising to a depth of 5 meters which is at a warmer temperature of 20 oC. What will be the volume of the diver’s lungs (in liters) at this 5-meter depth?  (Note:  The density of water is 1000 kg/m3 and an approximation for pressure with depth in water may be used.)
