Symbols Used to Denote Chemical Reactions or Process Conditions
Subscript Symbol Process
dilution (of a solution)
melting, fusion (solid → liquid)
mixing of fluids
reaction in general
solution (of solute in solvent)
sublimation (solid → gas)
transition (between two phases)
vaporization, evaporation (liquid → gas)
activated complex, transition state
°, θ standard
Examples of use could be:
r : Change in Gibbs free energy by (a given) reaction,
sol : Change in enthalpy by (a given) solution
vap : Change in entropy by (a given) evaporation
θ : Pressure at standard state (normally 1 bar)

Work, heat and energy systems.
The First Law of Thermodynamics simply states that energy can be neither created nor destroyed (conservation of energy). Thus power generation processes and energy sources actually involve conversion of energy from one form to another, rather than creation of energy from nothing.
