Change in the internal energy of gas Formula and Calculation
The change in the internal energy of gas formula derives from the mathematical expression of the First Law of Thermodynamics.
You must consider the following factors when using the First Law of Thermodynamics:
- ΔU is positive if the internal energy increases. (Temperature increases).
- ΔU is negative if the internal energy decreases. (Temperature decreases).
- Q is positive if heat is added to the system.
- Q is negative if heat flows out of the system.
- Wby the system is positive when work is done by the gas to lift the piston.
- Wby the system is negative when work is done on the gas, which results in a decrease in the volume.
