"Even as the engine and pilot consume the oxygen, it is mearly recombined in the H2O and CO2 expelled in the exhaust."
But surely the newly produced elements of Hydrogen and Carbon add their weight to the volume of the box.
Atomic weights of ;
Hydrogen = 1.00794
Carbon = 12.011
Oxygen = 15.9994
Let's say,
A 'unit' of oxygen = 16
A 'unit' of H20 = 1+1+16=18
A 'unit' of CO2 = 12+16+16=48
Total exhausted gases = 18+48=66
Doesn't the weight of exhausted gases therefore exceed original gases weight?
