Week 1 Revision of Thermodynamics Flashcards
what is the 0th Law of Thermodynamics
concept of thermal eqm leads to concept of Temp
in thermo eqm if at same temp
what is the 1st Law of Thermodynamics
dE = dQ + dW
what is the Kelvin Planck statement
Impossible to build an engine which in a cycle will produce no effect other than the extraction of heat and performance of work
what is the Clausius statement
Impossible to build a fridge which in a cycle will produce no effect other than the transfer of heat
what is entropy eqn
dS = dQ/T
what is always true of entropy
it never decreases and only remains 0 for reversible adiabatic processes
what is the FTR eqn
dE = TdS - PdV
what are the two Helmholtz Free energy eqns
F = E - TS dF = -SdT -PdV
what are the two Gibbs Free energy eqns
G = E -TS + PV dG = -SdT + VdP
