This calculator is used to determine the change in internal energy of a system based on heat added and work done.
Learn how to use the Change in Internal Energy Calculator and its working principle.
Enter the values for heat added (Q) and work done (W) in Joules. Click the "Calculate" button to determine the change in internal energy (ΔU) of the system.
The change in internal energy (ΔU) of a system is determined by the heat added to the system (Q) minus the work done by the system (W). This is based on the first law of thermodynamics.
