Laws of Thermodynamics
0th law: If system 1 is in thermal equilibrium with system 3, and system 2 is in thermal equilibrium with system 3, then system 1 and system 2 must also be in thermal equilibrium.
1st law: Energy transfer takes the form of heat and work.
2nd law: In an isolated system not in thermal equilibrium, the entropy almost always increases.
3rd law: As the temperature of a system nears zero, the entropy of the system nears a constant value.
- transfer of mechanical energy
- transfer of thermal energy
- transfer of particles (chemical)
For each of these processes the form of the energy transfer differs (1st law).
Transfer of mechanical energy: work is performed on or by the system
Transfer of thermal energy: heat is transferred from one object to another
Transfer of partcles: from this arises the law of conservation of energy which states that energy can be neither created nor destroyed
