We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

for 600s:

whole system (fluid and solid) total energy is conserved with 0.02% difference.

Air domain energy (mix) has 2.4% difference.

Air domain energy (ph-1 liquid water) has 0.6% difference. [117 g liquid water generated]

Air domain energy (ph-2 humid air) has 79% difference!!! [35C with 80% RH goes to 15.8C with 0.0015% RH]

Solid domain energy has 0.03% difference. [from 15C to 15.098C]

whole system energy change: 0.36e+06J 

whole system enthalpy change: 0.32e+06J 

mixture energy change: -0.05e+06J      

mixture enthalpy change: -0.099e+06J    

phase-1(liquid water) energy change: -0.4e+06J  

phase-1(liquid water) enthalpy change: -0.4e+06J 

phase-2(humid air) energy change: 1.8e+06J   

phase-2(humid air) enthalpy change: 1.8e+06J  

solid energy change: 0.4e+06J 

solid enthalpy change: 0.4e+06J
