(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Specify at least two ( physical or chemical), real world, processes for each of this cases:

a) Internal energy is constant

b) Entalpy is constant

c) Gibbs free energy is constant

d) Helmholtz free energy is constant

2. Relevant equations

a) dU = TdS - pDV = 0

b) dH = TdS + VdP = 0

c) dG = dH - tdS = 0, or dG =vDp -SdT = 0 ???

d) dF = -(pdV + SdT ) = 0

3. The attempt at a solution

b) Joulle-Thompson effekt

...and this is all what I found...

Thanks for any help !
