Significance of internal energy

Webw= -Pext (delta V). You need the negative in front because when work is done "on the system" (which is positive), delta V (Vfinal-Vinitial) is negative (the ballon is compressed). So the two negatives make the whole term for work positive. Side note: remember that external pressure (Pext) is considered constant. WebApr 9, 2024 · Helmholtz Free Energy Equation. A = U - TS .. eqⁿ1. U is the internal energy in Joules, T is the absolute temperature in Kelvin, and S is the final entropy in Joules per Kelvin (JK⁻¹). A stands for 'Arbeit' meaning work and is minimized to the equilibrium. Hermann von Helmholtz formulated it.
