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.

So I repeated this simulation with Ideal Gas laws for the density and other properties of the mixture and constant density for liquid water. after 100s physical time the results are as below:

Air energy change:+1.5e+06 J

Solid(Soil and pipe) energy change: +0.3e+06 J

Whole system energy change:+0.2e+06 J

Liquid water generated:101g which would have released 0.227e+06 J latent heat.

something still do not add up: where did the energy gained by air come from? can we say when the vapor content of the humid air cools down to reach dew point it releases this energy? if so, would it be possible to calculate or make an estimation for the amount of this energy?
