Returns nitrogen's heat capacity to the value it was pre-listmos math below

[NullNeska]

pre listmos (the values that will be inplace post-merge) O2 = 21.8366 N2 = 82.1472

O2_heat = 20 N2_heat = 20 air_heat = 20

O2+N2 * air_heat = O2 * o2_heat + n2 * n2_heat

2079.676 = 2079.676

post listmos O2 = 21.8366 N2 = 82.1472

O2_heat = 20 N2_heat = 300 air_heat = 20

O2+N2 * air_heat = O2 * o2_heat + n2 * n2_heat

2079.676 != 24644.16

additionally, it was proposed that the n2 be changed to 30: 2079.676 != 2464.616

also was proposed that n2 be 20 and oxygen be 10: 2079.676 != 1860.944
