The first law of thermodynamics states that when a system capable of doing external work is given a certain amount of heat, the amount of heat it absorbs is equal to the sum of the increase in the system’s internal energy due to temperature rise and the external work done by the system during expansion.
The first law of thermodynamics has the following equation:
ΔU = q + W
- ΔU = change in internal energy of the system.
- q = algebraic sum of heat transfer between system and surroundings.
- W = work interaction of the system with its surroundings.
