How internal energy of a gas can be changed
WebThe processes that change the internal energy are transfers, into or out of the system, of matter, or of energy, as heat, or by thermodynamic work. These processes are … WebThe internal energy U of a thermodynamic system is the energy it contains. It can be due to the motion of its particles (in the form of kinetic energy) and/or to their interactions. It generally depends on the state variables of the thermodynamic system (if it is a gas, p, V, T).. As it is a property of thermodynamic systems, the internal energy is a state function: …
