Assume that your lungs hold 2 liters of gas. a) If your lungs were filled with helium, calculate the total thermal energy of that helium. b) Assume instead, your lungs are filled with air. Calculate the mass of the air in yourlungs. (Assume that air is 20%O2and 80%N2).c) Calculate the total thermal energy of the air in your lungs. d) If you had a piece of metal with the same mass as the air in your lungs, how highabove the ground would the metal have to be for its gravitational potential energy tobe equal to the thermal energy of the air in your lungs?
