The Three Laws of Thermodynamics
1. Energy cannot be created or destroyed:
where U is the internal energy, Q is heat, W work.
2. There is no process who's sole effect is to transfer heat from a hot body to a cold body. Another way to put it is that no engine can convert energy from a heat reservoir entirely into mechanical energy.
Mathematically:
3. Entropy is zero at absolute zero.
where U is the internal energy, Q is heat, W work.
