The internal energy of a gas may be written U=C V nRT. I find that U(O 2)=3.285x10 7 J and U(H 2)=1.013x10 9 J before the ignition, so the initial internal energy of the system is U 1 =1.046x10 9 J. When ignition is complete, the energy added to the system is Q=44x286x10 3 =1.258x10 7 J and so U 2 =U 1 +Q=1.059x10 9 J.
