How internal energy of a gas can be changed
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: … Web27 feb. 2016 · My professor says the internal energy of a system can be calculated as U = n T c v. Now I always thought that we could only calculate a change in internal energy Δ U = n c v Δ T. Following this idea, he says that a recipient that contains gas and loses a certain number of moles at constant temperautre undergoes a change in internal …
