An air tank of volume 2.70 × 10−2 m3 has air pressure 7.30 × 106 Pa and temperature 30.0 ◦C inside and is left at a lake bottom at 15.0◦C. If there is a leak on the tank and the pressure and temperature inside have dropped to 2.70 × 106 Pa and 11.0 ◦C over a period of time.  How many moles of air are in the tank initially? (A) 70.2 mol; (B) 72.2 mol; (C) 74.2 mol; (D) 76.2 mol; (E) 78.2 mol.  How many moles of air have leaked out of the tank? (A) 39.3 mol; (B) 41.3 mol; (C) 43.3 mol; (D) 45.3 mol; (E) 47.3 mol.  What is the work done by the air leaked into the water? (A) 143 kJ; (B) 133 kJ; (C) 123 kJ; (D) 113 kJ; (E) 103 kJ.
