There are generally considered to be four principles (referred to as "laws"):
The zeroth law of thermodynamics, which underlies the definition of temperature.
The first law of thermodynamics, which mandates conservation of energy, and states in particular that heat is a form of energy.
The second law of thermodynamics, which states that the entropy of an isolated macroscopic system never decreases, or (equivalently) that perpetual motion machines are impossible.
The third law of thermodynamics, which concerns the entropy of a perfect crystal at absolute zero temperature, and implies that it is impossible to cool a system all the way to exactly absolute zero.
A bunch of bull my shaft wont be perpetual motion....................................
GET over it temp dont mean anything in my design...
@Skeee,
I assume you got that from some site. There are 4(major) things incorrect in your listing. Do you know what they are?
