Energy conservation for thermodynamic processes: the change in internal energy equals energy transferred as heat and work, with signs fixed by convention. Heat and work describe transfer paths rather than stored state variables.

Each relation below starts at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
The first law supplies the energy-balance constraint relating internal-energy change to heat and work transfers under a stated sign convention.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.
