Difference between e and u in thermodynamics

WebA. Internal Energy U In Thermodynamics, the total energy E of our system (as described by an empirical force field) is called internal energy U. U is a state function, which means, that the energy of a system depends only on the values of its parameters, e.g. T and V, and not on the path in WebThe internal energy and temperature of a system decrease (E < 0) when the system either loses heat or does work on its surroundings. Conversely, the internal energy and temperature increase (E > 0) …

WebYes, your concern has to do with the difference between open/closed systems. A closed system is one of constant mass (but the boundaries of the systems can change). An open system is one with mass flow in/out of the system. For a fixed mass of gas that expands, this is a closed system. For a closed system enthalpy due to mass flow does not ... WebThus, by the first law of thermodynamics, the work done for each complete cycle must be W = Q1 − Q2.
