Thermodynamics Calculator: First Law of Thermodynamics (ΔU)

Calculate Change in Internal Energy (ΔU)

Joules (J)
Enter the heat supplied to the system. Positive for heat added, negative for heat removed.
Joules (J)
Enter the work done by the system. Positive for work done by system, negative for work done on system.

Unlock the secrets of energy transfer with our free Thermodynamics Calculator. Easily compute the change in internal energy (ΔU) using the First Law of Thermodynamics: ΔU = Q - W. Ideal for students and professionals to quickly understand heat and work interactions in thermodynamic systems.

Formula:

The calculator applies the First Law of Thermodynamics, which states that the change in the internal energy of a closed thermodynamic system is equal to the amount of heat supplied to the system, minus the amount of work done by the system on its surroundings.

Formula: ΔU = Q - W

  • ΔU: Change in Internal Energy (Joules)
  • Q: Heat Added to the System (Joules)
  • W: Work Done by the System (Joules)
