The Second Law of Thermodynamics states that the entropy of the universe tends towards a maximum.
According to this law, it is impossible to build a perpetual motion machine, and entropy in a completely closed system must either increase or remain constant.
There are three different types of systems that the Second Law of Thermodynamics can apply to:
- Isolated system - Does not exchange matter or energy with its surroundings
- Closed system - Exchanges energy, but not matter, with its surroundings
- Open system - Exchanges both matter and energy with its surroundings
