For 10 points, name this thermodynamic law of conservation of energy.
Along with Fourier's equation, this law can be used to derive a parabolic partial differential equation that describes diffusion. When mass flow rate is constant, this law is often expressed as the SFEE, which contains an enthalpy plus one-half velocity squared plus gravitational acceleration times elevation term. In the statement of this law, two process functions commonly appear as inexact differentials and can be set equal to each other for an ideal gas undergoing an isothermal process. For an adiabatic process, this law can be stated as the work done depends only on the system's endpoint conditions. This law is commonly expressed as Q equals delta U plus W, or heat transferred equals the change in internal energy plus the work done by the system. For 10 points, name this thermodynamic law of conservation of energy.
