Answer
The First Law of Thermodynamics is a statement of the conservation of energy. It states that the change in the internal energy of a system is equal to the heat added to the system minus the work done by the system.
The formula is:
ΔU = Q - W
Where:
ΔU is the change in internal energy
Q is the heat added to the system
W is the work done by the system
