railway RRB JE (CBT I + CBT II) Mock Test 2024 Thermodynamics Availability and Irreversibility Helmholtz and Gibbs Function
Which of the following is CORRECT?
[A = Helmholtz function (Helmholtz Free Energy), G = Gibbs function (Gibbs Free Energy), U = Internal energy, H = Enthalpy, T = Absolute temperature, S = Entropy]
1
A = H - TS ; G = H + TS
2
A = U - TS ; G = H - TS
3
A = U + TS ; G = H - TS
4
A = U - TS ; G = U + TS
