1st Law of Thermodynamics.
dE = dQ + dW.
dE = dQ - PdV.
2nd Law of Thermodynamics.
dS = dQ/T.
dQ = TdS.
By Combining 1st and 2nd Laws of Thermodynamics;
dE = TdS - PdV.
dE = dQ + dW.
dE = dQ - PdV.
2nd Law of Thermodynamics.
dS = dQ/T.
dQ = TdS.
By Combining 1st and 2nd Laws of Thermodynamics;
dE = TdS - PdV.
