Significance of internal energy
WebSolution. To evaluate this integral, we must express p as a function of V. From the given equation of state, the gas pressure is. p = R T V − b − a V 2. Because T is constant under the isothermal condition, the work done by 1 mol of a van der Waals gas in expanding from a volume V 1 to a volume V 2 is thus. WebMay 10, 2024 · Sorted by: 1. Standard Definition : The internal energy of a system is identified with the random, disordered motion of molecules; the total (internal) energy in a system includes potential and kinetic energy. Since this molecular motion is primarily a function of temperature, the internal energy is sometimes called 'thermal energy'.
