What is the scientific explanation for why deltaH = q when pressure is constant?
Also, why is deltaU (internal energy) = q when volume is constant?
When either pressure or volume is constant, shouldn't the PdeltaV variable be eliminated? In that case, why wouldn't deltaH = deltaU = q in both situations?
