The internal energy calculator allows you to calculate the change in internal energy of a system with a given input and output heat and input and output work. 
The system increased its internal energy by 12 J due to increase of its temperature (more heat received). In physics, a more common way to view the internal energy of a system is in terms of its macroscopic characteristics, which are very similar to atomic and molecular average values.įrom the macroscopic point of view, the change in internal energy ΔU is defined as the difference between the energy received Q (as heat) and energy lost W (as work). Internal energy includes kinetic energy of translation, rotation, and vibration of molecules, potential energy within molecules, and potential energy between molecules. In other words, internal energy is all the energy of a system that is associated with its microscopic components (consisting of atoms and molecules), when viewed from a reference frame at rest with respect to the object. Since the sum of kinetic energy and potential energy is the mechanical energy, the internal energy of a system is the sum of atomic and molecular mechanical energy. microscopic (atomic and molecular view)įrom the microscopic point of view, which examines the system on the atomic and molecular scale, the internal energy U of a system is the sum of the kinetic and potential energies of its atoms and molecules.
Internal energy can be defined in two ways: Internal energy is the energy possessed by a system.
