a generalization that describes recurring facts or events in nature

the science of matter and energy and their interactions

a law stating that mechanical work can be derived from a body only when that body interacts with another at a lower temperature; any spontaneous process results in an increase of entropy

law stating that the entropy of a substance approaches zero as its temperature approaches absolute zero

the law that if two bodies are in thermal equilibrium with a third body then the first two bodies are in thermal equilibrium with each other

the fundamental principle of physics that the total energy of an isolated system is constant despite internal changes
